ABSTRACT:
The invention provides an electrophotographic photoreceptor comprising a conductive substrate having a photosensitive layer and a protective layer thereon, the protective layer comprising a crosslinked film having a phenolic structure, in which the relationship between a pH of the exfoliated protective layer extracted with distilled water (pHOCL) and a pH of said distilled water (pHw) satisfies the following formula (A):pHOCL−pHW≦0.5.
