摘要： An image forming apparatus having excellent cleaning property for an electrophotographic photoreceptor and capable of forming a high-quality, high-resolution image. A surface free energy (γ) of a photoreceptor (2), which is provided in the image forming apparatus (1), is set to 20 to 35 mN/m. 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.

摘要： An object of the invention is to provide an image forming apparatus being excellent in cleaning property for an electrophotographic photoreceptor and capable of forming a high-quality, high-resolution image. A surface free energy (γ) of a photoreceptor (2) which is provided in the image forming apparatus (1) and is exposed to a light corresponding to image information for formation of an electrostatic latent image is set to 20 to 35 mN/m. A volume average diameter of a 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 mum. 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 hence increased in specific surface area and largely affected by a inter-molecular force is limited in adhesion force to the surface of the photoreceptor (2) to provide a good cleaning property, whereby a cleaning property is enhanced and at the same time a high-quality image can be formed.

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.
摘要翻译：在包括导电基片和形成在导电基片上的感光层的电子照相感光体中，其中将均匀带电的感光层暴露于对应于图像信息的光以形成静电潜像，表面自由能（γ）被确定为至少20mN / m和最多35mN / m。感光体1的表面上的γ测定在适当的范围内可以抑制调色剂对感光体的表面的过度粘附，抑制异物如纸粉的粘附，并使其易于分离从表面，这导致改善感光体的可清洁性。由于图像由始终具有清洁表面的感光体1形成，所以在长时间内不会发生损坏或图像质量的降低。

摘要： The invention provides an electrophotographic photoreceptor, in which suppression of image defects and high sensitivity are compatible, and a method for production thereof. The invention also provides a coating fluid for forming a photosensitive layer and a method for production thereof, as well as an image-forming apparatus using said electrophoto-graphic photoreceptor. Briefly, the electrophoto-graphic photoreceptors may be constructed by forming an undercoating layer on a conductive support, and then forming a photosensitive layer on the undercoating layer. The undercoating layer contains titanium oxide particles in at least either needle shape or dendrite shape. The photosensitive layer contains an electric charge-generating material of which the primary particle size and cohesive particle size are in a range of 0.01 &mgr;m-10 &mgr;m. Accordingly, in the electrophotographic photoreceptors, it is possible to maintain high sensitivity and excellent durability and to form an image with no defect. The photosensitive layer in the electrophotographic photoreceptor has a multilayer structure consisting of a charge-generating layer and a charge-transporting layer. The charge-generating material is a phthalocyanine pigment.
