Summary:PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that reduces local wear of a surface in a non-image forming area of the electrophotographic photoreceptor.SOLUTION: There is provided an electrophotographic photoreceptor including a charge generating layer that contains at least one of a titanyl phthalocyanine pigment and a gallium phthalocyanine pigment, and a charge transport layer that contains at least one of a polycarbonate resin and a polyarylate resin, where a non-image forming area of the electrophotographic photoreceptor has an area α where the thickness of the charge generating layer in the non-image forming area is smaller than the thickness of the charge generating layer in an image forming area.SELECTED DRAWING: None 【課題】 電子写真感光体の非画像形成領域における局所的な表面の摩耗を低減する電子写真感光体を提供する。【解決手段】 電荷発生層が、チタニルフタロシアニン顔料およびガリウムフタロシアニン顔料の少なくとも一方を含有し、電荷輸送層が、ポリカーボネート樹脂およびポリアリレート樹脂の少なくとも一方を含有し、電子写真感光体の非画像形成領域中に、非画像形成領域中の電荷発生層の膜厚が該画像形成領域の電荷発生層の膜厚よりも薄い領域αを有する事を特徴とする電子写真感光体。【選択図】 なし
