ELECTRIFYING DEVICE FOR IMPRESSING UNIFORM ELECTROSTATIC CHARGE ON CHARGE HOLDING SURFACE, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC PRINTER

摘要

PROBLEM TO BE SOLVED: To provide a printer provided with an electrifying device for impressing a uniform electrostatic charge on the charge holding surface through minimizing the generation of ozone. SOLUTION: In this electrifying device 76, at least one of the level of a current in a power source 322, the level of a voltage in the power source 322, the effective electrostatic charging length of an electrode 314 and the effective grid width of the grid 336 is selected in order to optimize the uniformity in charging, to reduce the sensitivity to the light receiving grid sensitivity as much as possible and to minimize the ozone generated in a corotron 76.
