ABSTRACT:
The invention provides a process for producing a negative-charging electrophotographic photosensitive member which can improve the adherence between a first layer and a second layer without lowering the effect of lessening image defects and realize a reduction in overall costs, a negative-charging electrophotographic photosensitive member produced by the process, and an electrophotographic apparatus. In the process for producing a negative-charging electrophotographic photosensitive member, a first layer is deposited on a substarte, at least the vertexes of protuberances are removed, the substrate with the first layer deposited theron is placed in a film forming furnace, the first layer surface is plasma-treated with a gas containing at least a Group 13 element in the periodic table and a dilution gas composed of at least one selected from hydrogen, argon and helium, and a layer formed of a non-single-crystal material is deposited as the second layer on the first layer.
