电子照相感光体，其制造方法，处理盒和成像装置

Electrophotographic photoreceptor, method of producing the same, process cartridge, and image-forming apparatus
Abstract:
The invention provides an electrophotographic photoreceptor that includes a cylindrical support, and a charge-generating layer and a charge-transporting layer on the cylindrical support, wherein a content per unit volume of a charge-generating material in the charge-generating layer increases from a center portion in an axial direction of the cylindrical support towards both end portions thereof, and a thickness of the charge-generating layer in an axial direction of the cylindrical support is 95% or more and 105% or less relative to an average thickness of the charge-generating layer.
