摘要： A method of charging a photoreceptor (3) includes a first corona charging unit (2) a first corona electrode (4), a first shell electrode (6), and a first high voltage power supply (22). The shell electrode is connected through a resistor to ground and the high voltage power supply is connected to the first corona electrode. A second corona charging unit (10) has a second corona electrode (12), and a first grid electrode (14) connected to a second shell electrode (16). A first corona current from the first high voltage power supply to the first corona electrode and a return current from the first shell electrode to ground is sensed and a voltage on the first high voltage power supply is adjusted to maintain a constant difference. The first corona charging unit charges the photoreceptor to at least 63% of the desired voltage.

摘要： A method of removing charge from a charged sheet prior to stacking the charged sheet is disclosed. The method includes moving the charged sheet through a set of nipped rollers while a first roller has an AC voltage applied thereto so that a first side of the charged sheet is in contact with the first roller and has its charge substantially dissipated, whereby charge substantially remains on a second side of the charged sheet in contact with a second roller. The method further includes using at least one non-contact charge removal device to remove charge from the second side of the charged sheet, and stacking the discharged sheet.

摘要： A toner particle image made up of toner particles having a mean particle diameter of less than 7 microns and transfer-assisting particles strongly adhering to the surfaces of the toner particles having a mean particle diameter between about 0.01 microns and about 0.2 microns is electrostatically transferred to an intermediate. An intermediate has a base having a Youngs modulus of 10.sup.7 Newtons/m.sup.2 or less and a thin overcoat or skin which has a Youngs modulus of 5.times.10.sup.7 Newtons/m.sup.2 or more. The toner image is then electrostatically transferred from the intermediate image member to a receiving sheet. The surface of the intermediate image member receiving the toner image preferably has a roughness average equal to 20% of the mean diameter of the toner particles or less.

摘要： A method and apparatus for determining the charge-to-mass ratio of electroscopic toner particles of the type used in electrostatographic recording to develop electrostatic images. The apparatus uses a biased electrode for attracting toner particles thereto, and a microprocessor-based logic and control unit for sampling the mass of toner particles deposited on the electrode after the deposited toner particles have neutralized the electric field produced by the electrode bias. This toner mass information, together with certain toner constants and known parameters, is used by the logic and control unit to calculate the toner's charge-to-mass ratio. The output of the apparatus is useful for controlling process parameters (e.g. primary charging and exposure levels, development electrode bias, toner concentration) which affect image quality.
