Abstract: A single-layer-type electrophotographic photosensitive member includes a layer disposed on an electrically conductive substrate, the layer including at least a charge-generating material, an electron transport material, a hole transport material, and a binder resin within the same layer. The charge-generating material contains a phthalocyanine pigment and N-type pigments including at least a perylene-based pigment and an azo-based pigment, and the total amount of the N-type pigments is 0.03 to 10 parts by mass relative to 1 part by mass of the phthalocyanine pigment.

Abstract translation: 单层型电子照相感光构件包括设置在导电基板上的层，该层至少包括在同一层内的电荷产生材料，电子传输材料，空穴传输材料和粘合剂树脂。 电荷产生材料含有酞菁颜料和至少包含苝基颜料和偶氮类颜料的N型颜料，并且N型颜料的总量相对于1份为0.03〜10质量份 的酞菁颜料。
