Electrophotographic apparatus, process cartridge and image forming method

摘要

An electrophotographic apparatus is constituted by an electrophotographic photosensitive member (1), and charging means, imagewise exposure means (3) and developing means (4) disposed in this order opposite to the photosensitive member (1). The photosensitive member (1) has a surface layer comprising a charge-injection layer. The charging means includes a charging member (2) comprising magnetic particles (2a) and disposed contactable to the photosensitive member so as to charge the photosensitive member based on a voltage received thereby. The magnetic particles have a volume resistivity in the range of 1x10<4> - 1x10<9> ohm.cm, and the magnetic particles have a surface layer having a volume resistivity of at most 1x10<9> ohm.cm. <IMAGE>
