Electrophotographic photorecptor

The present invention provides an electrophotographic photoreceptor, a cartridge, and an image forming apparatus, wherein the electrical potential change following strong light exposure of the photoreceptor is suppressed and wherein the mechanical properties of filming and wear resistance are improved. The present invention relates to an electrophotographic photoreceptor that comprises an electric charge generating layer on a conductive substrate, and an electric charge transport layer having a film thickness of 15-40 [mu]m, the electrophotographic photoreceptor being characterized in that the electric charge transport layer is an outermost layer and the electric charge transport layer comprises an inorganic filler and a hydrocarbon compound represented by formula (I). 本发明提供种感光体的强曝光暴露后的电位变化得到抑制、成膜及耐磨耗性的机械特性提高的电子照相感光体、盒、图像形成装置。本发明涉及种电子照相感光体，其特征在于，其在导电性基体上具有电荷产生层及膜厚为15μm以上且40μm以下的电荷传输层，该电荷传输层为最外层，该电荷传输层含有无机填料和下述通式(1)所示的烃化合物。
