Electrophotographic photoreceptor, process cartridge, and image forming apparatus

摘要

An electrophotographic photoreceptor includes a conductive substrate, a photosensitive layer that is provided on the conductive substrate, and a surface layer that is provided on the photosensitive layer or is contained in the photosensitive layer, wherein the surface layer is formed of a cured film of a composition including a first reactive charge transport material having a hydroxyl group and a second reactive charge transport material having a methoxy group, and has an elastic deformation ratio R satisfying the following Expression (1):
0.40≦R≦0.51.

1. An electrophotographic photoreceptor comprising:
a conductive substrate; a photosensitive layer that is provided on the conductive substrate; and a surface layer that is provided on the photosensitive layer,
wherein the surface layer is formed of a cured film of a composition including
a guanamine compound;a first reactive charge transport material having a hydroxyl group and a second reactive charge transport material having methoxy groups; anda catalyst,wherein the cured film has an elastic deformation ratio R satisfying the following Expression (1):
0.40≦R≦0.51  (1),and
a blending ratio of the catalyst is from 0.1% by weight to 50% by weight with respect to all of the solid contents of the surface layer excluding any fluorine resin particles present in the composition and any fluorinated alkyl group-containing copolymers present in the composition.
