Abstract:
1. An electrophotographic photoreceptor, comprising an electroconductive substrate having provided thereon a photosensitive layer, an outermost layer of the photosensitive layer having a dynamic hardness of from 20.0×10 9 to 100.0×10 9 N/m 2 ; wherein the dynamic hardness is a value calculated by the following equation (1) using a penetration load and a penetrating depth when a diamond penetrator having a tip angle of 115° and a tip curvature radius of 0.1 μm or less is penetrated onto the outermost layer of the electrophotographic photoreceptor with a stress velocity of 0.05 mN/sec: wherein DH represents the dynamic hardness (N/m
