| Zusammenfassung: | To provide an electrophotographic photoreceptor that reduces the likelihood of the occurrence of a problem in thin line reproducibility in output of images at high resolution, while maintaining satisfactory electrical characteristics.SOLUTION: An electrophotographic photoreceptor has a support, an undercoat layer formed on the support, and a photosensitive layer formed on the undercoat layer. In the electrophotographic photoreceptor, the undercoat layer contains resin and surface-treated metal oxide particles, and the surface treatment is performed with a silane coupling agent having an isocyanurate group in a molecule.SELECTED DRAWING: None
【課題】良好な電気特性を維持しつつ、高解像度での画像出力において細線再現性の不具合が生じにくい電子写真感光体を提供する。【解決手段】支持体、該支持体上に形成された下引き層、ならびに該下引き層上に形成された感光層を有する電子写真感光体において、該下引き層が、樹脂、および表面処理された金属酸化物粒子を含有し、該表面処理が、分子内にイソシアヌレート基を有するシランカップリング剤による表面処理である電子写真感光体。【選択図】なし |
