Title:
電子写真感光体、プロセスカートリッジ、画像形成装置
Document Type and Number:
Japanese Patent JP6520191
Kind Code:
B2
Abstract:
An electrophotographic photoreceptor includes a conductive substrate, and a single-layer type photosensitive layer that contains a binder resin, a charge generating material, a hole transporting material, and an electron transporting material, wherein a content of the charge generating material in the photosensitive layer is 0.5% by weight or more and less than 2.0% by weight and the charge generating material satisfies expression (1): 30≦a/b, wherein a represents the number of the charge generating materials per unit cross-sectional area in a region ranging from the surface side of the film thickness of the photosensitive layer to a point corresponding to ⅓, and b represents the number of the charge generating materials per unit cross-sectional area in a region ranging from the conductive substrate side of the film thickness of the photosensitive layer to a position corresponding to ⅔, provided that a case where b is 0 is included.
