Abstract
An electrophotographic photoreceptor includes a conductive substrate, a photosensitive layer, and a surface layer that is provided on the photosensitive layer. The surface layer includes a cross-linked component which is a reaction product of compound A and compound B. The compound A is at least one compound selected from guanamine compounds and melamine compounds, and the compound B is a charge-transporting material. A structure derived from at least one compound selected from the guanamine compounds and the melamine compounds included in the surface layer amounts for 0.1% by weight to 5% by weight, and a structure derived from the charge-transporting material included in the surface layer amounts for 85% by weight or greater. Surface roughness Rz of the surface layer is from 0.1 μm to 0.3 μm, and the surface has at least one compound selected from fatty acid metal salt and fluorine resin particles.
