Cartridge utilizing a plurality of contact charging members |
摘要 |
Cartridge (1) contains a brush charger (32) and printer (40) contains a charge roller (30). Upon installation of the cartridge a top shutter (7) is moved downward and the charge roller is moved by a pivoted arm (44) through the opening left by the shutter to contact a photoconductor drum (24) in the cartridge. In operation the roller functions after charging by the brush at a potential to control the final charge on a photoconductor prior to xerographic imaging. The precharging by the brush greatly reduces deterioration of the charge roller, permitting long machine life with the accurate and uniform operation of a charge roller.
