摘要： In an electrophotographic photoreceptor including a conductive substrate and a photoreceptive layer formed on the conductive substrate wherein the photoreceptive layer charged uniformly is exposed to light corresponding to an image information to form an electrostatic latent image, the surface free energy (γ) is determined to be at least 20 mN/m and at most 35 mN/m. The determination of γ on the surface of the photoreceptor 1 in the appropriate range makes it possible to suppress excessive adhesion of a toner to the surface of the photoreceptor, to suppress adhesion of foreign matters such as a paper powder and to make easy the separation thereof from the surface, which results in improving the cleanability of the photoreceptor. Since the image is formed with the photoreceptor 1 having always the clean surface, the damage or the decrease in image quality does not occur over a long period of time.

A volume average diameter of toner particles included in a developer stored in a developing unit (29) to develop an electrostatic latent image and form a toner image is set to 4-7 μm When γ of the photoreceptor (2) is set to within a small range as the particle size of toner is reduced, even small-particle-size toner having increased specific surface area and largely affected by a inter-molecular force is limited in adhesion to the surface of the photoreceptor (2) to provide a good cleaning property and a high-quality image can be formed.
