PROCESSING CARTRIDGE FOR LASER PRINTER

摘要

A processing cartridge (100) for a laser printer, comprising: a photosensitive drum (101), a developing roller (105) and a toner delivery roller (117).A doctor blade (113) extending along the axial direction of the developing roller (105) and the cylindrical face of the developing roller (105) and a sealing plate (114) divide the developing roller (105) into an exposed working face (115) and a hidden adsorption face (118).The processing cartridge (100) also comprises an elastic mechanism (121) for pressing a part of the sealing plate (114) in contact with the cylindrical face of the developing roller (105) towards the cylindrical face of the developing roller (105).Using the processing cartridge (100) as a laser photography imaging device can effectively eliminate the occurrence of toner leakage due to falling off or vibrating during transportation.
