摘要： The electrophotographic photoreceptor of the present invention includes a cylindrical support; a charge-generating layer and a charge-transporting layer that are layered onto the cylindrical support in this sequence from the cylindrical support side. The charge-transporting layer includes a charge transport material, and resins including a curable resin and a thermoplastic resin. The proportion of the content of the curable resin with respect to the total amount of the resins in the charge-transporting layer increases in the layer thickness direction with distance from the charge-generating layer side.
