Summary:PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor having extremely good wear resistance while maintaining a residual potential, a cartridge employing the electrophotographic photoreceptor, and an image forming apparatus.SOLUTION: An electrophotographic photoreceptor has a photosensitive layer on a conductive support. The photosensitive layer contains a binder resin having a bisphenol component of a specific structure in an amount of 25 mol% or more based on all bisphenol components, and a compound represented by a specific general formula (1) with a molecular weight of 350 or less.SELECTED DRAWING: None 【課題】残留電位を維持したまま、極めて良好な耐摩耗性を有する電子写真感光体、電子写真感光体を用いたカートリッジ、及び画像形成装置を提供する。【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、感光層が特定構造のビスフェノール成分を全ビスフェノール成分中２５モル％以上有する結着樹脂、及び特定の一般式（１）で表される分子量３５０以下の化合物を含有する。【選択図】なし
