PROBLEM TO BE SOLVED: To provide a high-resolution electrophotographic photoreceptor which has a surface protective layer of an optically uniform state free of light scattering and bleeding and with which low surface energy, the mechanical characteristics, such as hardness and strength, and the electrical durability, such as arc discharge resistance, are made compatible and an electrophotographic image forming device having this photoreceptor. SOLUTION: This electrophotographic photoreceptor is the electrophotographic photoreceptor having a photosensitive layer on a conductive base. The surface protective layer of this photoreceptor contains the condensation product of the compd. expressed by formula by the following general formula: R2 SiO3/2 and/or RSiO3/2 , (R denotes at least one group selected from the group consisting of 1-3C alkyl group, vinyl group, Cn F2n +1 C2 H4 -group (n=1 to 18),γ-glycideoxypropyl group, y-methacryloxypropyl group). This electrophotographic image forming device uses this photoreceptor.
