ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS

The invention relates to an electrophotographic photoreceptor, a process cartridge, and an image forming apparatus. The present invention provides an electrophotographic photoreceptor in which the occurrence of multiple color ghosting is suppressed. The electrophotographic photoreceptor includes a conductive substrate having a surface, an undercoat layer disposed on the surface of the conductive substrate, and a photosensitive layer on the undercoat layer. A maximum height waviness of a waviness profile of the surface of the conductive substrate on which the undercoat layer is disposed is 1.4[mu]m or less, and the undercoat layer contains a binder resin and has a thickness non-uniformity of 0.4 [mu]m or less. 本发明是涉及一种电子照相感光体、处理盒及图像形成装置。本发明提供一种多重色重影的产生得到抑制的电子照相感光体。所述电子照相感光体，其包括：导电性基体，供底涂层设置的面的波纹度曲线的最高波纹度为1.4μm以下；底涂层，设置于所述导电性基体上，并且包含粘结树脂且膜厚不均为0.4μm以下；以及感光层，设置于所述底涂层上。
