Zusammenfassung:	To provide an electrophotographic photoreceptor that maintains high transferability for a long period.SOLUTION: An electrophotographic photoreceptor has a surface layer containing inorganic particles and a binder resin. The binder resin is a polymer of a polymerizable monomer composition containing a polymerizable monomer having a polymerizable functional group. The polymerizable monomer composition contains a polymerizable monomer A indicated by the formula (1) as the polymerizable monomer. The value of the ratio of the volume of the inorganic particles to the volume of the binder resin in the surface layer is 0.5 or more and 3.0 or less.SELECTED DRAWING: Figure 1 【課題】高い転写性が長期間維持する電子写真感光体を提供する。【解決手段】無機粒子及び結着樹脂を含有する表面層を有する電子写真感光体であって、該結着樹脂が、重合性官能基を有する重合性単量体を含有する重合性単量体組成物の重合体であり、該重合性単量体組成物が、該重合性単量体として、式（１）で示される重合性単量体Ａを含有し、該表面層における該結着樹脂の体積に対する該無機粒子の体積の比の値が、０．５以上３．０以下である。【選択図】図１
