Summary:PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that is excellent in abrasion resistance to a practical load and electrical property.SOLUTION: There is provided an electrophotographic photoreceptor comprising a photosensitive layer on a conductive support, wherein the photosensitive layer contains a polyester resin having a repeating unit of a divalent carboxylic acid residue and a divalent phenol residue represented by the following formula (1). In the formula (1), Rand Rare each independently represent an alkyl group having 1 to 10 carbon atoms, an alkoxyl group having 1 to 10 carbon atoms, an alkyl halide group, or a benzyl group; X represents an alkylene group having 1 to 10 carbon atoms; n and m represent an integer of 0 to 4.SELECTED DRAWING: None 【課題】実用上の負荷に対する耐摩耗性及び電気特性に優れた電子写真感光体を提供する。【解決手段】導電性支持体上に感光層を有する電子写真感光体において、前記感光層が、下記式（１）で表される２価カルボン酸残基、及び２価フェノール残基の繰り返し構造を有するポリエステル樹脂を含有する、電子写真感光体。（式（１）中、Ｒ１、Ｒ２はそれぞれ独立に、炭素数１〜１０のアルキル基、炭素数１〜１０のアルコキシル基、ハロゲン化アルキル基、又はベンジル基を示す。Ｘは炭素数１〜１０のアルキレン基を示し、ｎ、ｍは、０〜４の整数を示す。）【選択図】なし
