An electrophotographic photoreceptor having excellent chargeability without a decrease in sensitivity at initial and repeated use, and a method for producing the same, even when a non-halogen solvent is used in a coating liquid for a charge transport layer, An image forming apparatus and an electrophotographic process cartridge using the electrophotographic photosensitive member. Kind Code: A1 An electrophotographic photosensitive member comprising a conductive support, on which at least a charge generation layer and a charge transport layer formed using a non-halogen solvent are sequentially laminated, wherein an electroconductive photoconductor is provided in the charge generation layer. A charge generating material having an average particle diameter smaller than the surface roughness of the porous support, and a polyvinyl acetal resin having a ratio (Mw / Mn) of the weight average molecular weight (Mw) to the number average molecular weight (Mn) of 2.2 or more. An electrophotographic photoreceptor, comprising: [Selection diagram] Fig. 1 |
