Document Type and Number:
WIPO Patent Application WO/2022/260036
Kind Code:
A1
Abstract:
The present invention provides an electrophotographic photoreceptor that achieves good transferability. Provided is an electrophotographic photoreceptor formed by stacking a charge generation layer, a charge transport layer, and a protection layer in this order on a support, the electrophotographic photoreceptor being characterized in that the protection layer contains a binder resin and particles, and when, in the cross-section of the protection layer, the mean film thickness of the protection layer in a portion not containing the particles is denoted by T, and the volume mean particle diameter of the particles is denoted by Dm, expression (a) is satisfied. Expression (a): Dm > T
