	U.S. Patent: 5527652 - Organic photoconductor - June 18, 1996
		An organic photoconductor 100 is mounted on the drum and is stretched tight by stretchers 99.
		Following transfer of the toner image to substrate 130, photoconductor 100 is engaged by a cleaning roller 50, which typically rotates in a direction indicated by an arrow 52, such that its surface moves in a direction opposite to the movement of adjacent surface of photoconductor 100 which it operatively engages.
		According to one embodiment of the invention, organic photoconductor 100 is mounted on a stretcher 120 and tensioned to a strain of 3 Kg per cm of width of photoconductor 100.

	U.S. Patent: 6124072 - Photoconductor for electrophotography and method of manufacturing and using a photoconductor - ...
		A method of manufacturing a photoconductor is also disclosed, which includes forming a photoconductive layer by vapor deposition on a conductive substrate and thermally treating the photoconductive layer at a temperature between 100 and 200 degrees Celsius for a period between 30 and 80 minutes.
		In an exposure section 2, the photoconductor 10 is exposed to light in a pattern corresponding to the image to be produced.
		The period of time between when the photoconductor is first exposed to light and when the potential of the photoconductive layer surface drops is determined by the migration period of the negative charge carriers.

	Photoconductor with charge generation binder blend - Patent 6042980
		Charge generation layers for photoconductors comprise a binder and a charge generation compound, wherein the binder comprises a blend of polyvinylbutyral polymer and at least one resin which improves at least one electrical characteristic of a photoconductor in which the charge generation layer is included.
		Photoconductors including charge generation layers formed from these binders generally exhibit good electrical characteristics, but the adhesion of the charge generation layers to the substrates are typically relatively poor, particularly at high temperature and/or high humidity conditions.
		The photoconductors according to the invention exhibited good overall adhesion, similar to that of the comparative photoconductors and significantly better than that of conventional photoconductors wherein the charge generation layer is formed from a hydroxy squaraine solution or from a copolyestercarbonate-hydroxy squaraine dispersion.

	Photoconductor tensioning device - Patent 4357093
		A clamping device for securing a photoconductor in the form of a closed loop, flexible sleeve on a drum having a channel on the drum periphery, and with the channel running substantially parallel to the drum central axis, along the length of the drum, is disclosed.
		Moreover, the useful life of a photoconductor may be cut short substantially because of physical damage to the photoconductor sheet due to foreign objects, and mishandling during the clearance of a paper jam performed either by an operator or a service person.
		In addition, photoconductor replacement may also be necessitated by damages to the photoconductor sleeve 12 caused during the clearance of a paper jam performed by an operator.

	Physics 106 - How Things Work - Problem Set #4 - Solutions
		Answer: For the voltage on the photoconductor surface were to exceed 10,000 volts, something would have to do work on the (positive) charge to transfer it from the thin wire to the photoconductor surface and there isn't anything to do that work.
		The photoconductor surface is supported by a metal cylinder that’s connected by a wire to the earth.
		A small patch of the photoconductor is then exposed to red light from a document and 0.000001 coulomb (one millionth of a coulomb) of charge crosses from the outside surface to the inside surface of the photoconductor.

	Apparatus and method for low sensitivity corona charging of a moving photoconductor - Patent Review 4245272 (Site not responding. Last check: 2007-11-03)
		Primary charging of a moving electrographic photoconductor to a nominal potential level is achieved with low sensitivity to variation in system parameters, such as photoconductor capacitance, photoconductor velocity and/or charger efficiency.
		Separately-addressed, AC corona discharge units are arranged and predeterminedly biased to first substantially overcharge the photoconductor relative to the nominal potential and then discharge the photoconductor to exit at the nominal potential level.
		From the abscissa origin to L/2 each photoconductor is subjected to a charger biased generally to an overcharge potential V.sub.b1 and from L/2 to L the photoconductor is subjected to a charger biased generally toward discharge potential V.sub.b2.

	Laser Printers
		This photoconductor is charged with even electrostatic charge by either a corona wire or primary charge roller, erasing old images from the OPC drum and prepping the charge of the drum to receive new images.
		In this excited state the toner is very receptive to the charge created by the laser on the Photoconductor drum surface and is less receptive to the areas which were not truck by the laser.
		The photoconductor, still rotating, reaches the wiper blade which removes any remaining toner from the Photoconductors surface and deposits the waste toner in the waste chamber.

	How Things Work - Xerographic Copiers
		Naturally, the photoconductor used in such a complicated machine must be sensitive to the whole visible spectrum of light.
		A photoconductor is a material that only conducts electricity when exposed to light, so that charges can move through the photoconductor only when the laser beam hits it.
		Wherever light from the white portions of the document strikes the photoconductor, the photoconductor becomes an electric conductor and charge is able to move.

	Enhancement of sensitivity by stratifying a photoconductor on thermoplastic-photoconductor media
		On thermoplastic-photoconductor media, the holographic characteristics and the enhancement of sensitivity for light intensity have been studied and it is found that the diffraction efficiency depends strongly upon the intensity of laser light and that the sensitivity becomes higher as the thickness of single layer photoconductor increases.
		Double layer and a triple layer photoconductor systems which are more sensitive than a usual single layer have been developed.
		The main reason for the sensitivity enhancement of the triple layer photoconductor system is to absorb the charge carriers which are injected or cannot arrive at the transparent conductor.
