Abstract
There is provided an image forming apparatus wherein the life of the photosensitive member is not extremely limited by scratches, abrasion, or the like. Also, there is provided an image forming apparatus free from such problems as image blurring due to products formed by electric discharge or foreign matters like paper powder (talc) transferred from the paper. Further, in an image forming apparatus for forming an image using an electrophotographic photosensitive member through the cycle of charging, latent image formation, development, and transfer, abrasion of the surface layer of said electrophotographic photosensitive member is in the range of 0.1 to 2.0 nm by the use of 1 kilocycle. An example of the preferred embodiments includes a charging device, exposing device, toner developing device, and transfer device disposed in the order of process sequence, and at least the charging device and the transfer device spaced from the electrophotographic photosensitive member.
