摘要： A photosensitive element is produced with a minimum amount of a conductive synthetic resin material. A draft for injection molding is formed in the inner circumferential surface as a supporting body, and a driven member provided with a gear is fixed to the end of the supporting body with a smaller inner diameter, that is, the thicker end. A driven portion in which a plurality of projections and depressions are formed alternately to be adjacent to each other in the circumferential direction is arranged on an axial end of a cylindrical supporting body made of a conductive synthetic resin, including a photosensitive layer on the outer circumferential surface. By a joint member removably engaged with the driven portion, the supporting body is rotated around the axis. In one arrangement, only the end of the supporting body is solid. In another arrangement, the supporting body is solid in the almost entire length in the axial direction.

摘要： A non-magnetic mono-component toner of the present invention is composed of a coloring powder at least containing a binder resin, coloring agent and wax and at least one kind of external additive having a mean particle diameter of 0.04 μm or greater, wherein the relationship between the Vickers hardness of the above coloring powder and the mean particle diameter of the external additives satisfies the predetermined expression. Thereby, the present invention is effective in preventing the external additive particles from sinking into the toner surface as well as from falling off from the surface when the toner particles are stressed in the developing unit. As a result, it is possible to provide stable image quality free from degradation of toner charge performance and toner supply performance even for long-term use.
摘要翻译：本发明的非磁性单组分调色剂由至少含有粘合剂树脂，着色剂和蜡的至少一种平均粒径为0.04μm以上的外部添加剂的着色粉末组成，其中，上述着色粉末的维氏硬度与外部添加剂的平均粒径之间的关系满足规定的表达式。因此，本发明在调色剂颗粒在显影单元中被应力时有效地防止外部添加剂颗粒沉入调色剂表面以及从表面脱落。结果，即使长期使用也可以提供稳定的图像质量，而不会降低调色剂充电性能和调色剂供应性能。

摘要： An image forming apparatus having a tandem system configuration, includes: a multiple number of photoreceptors which each form an electrostatic latent image; and a multiple number of developing devices each holding a different color toner from the others for development of the corresponding static latent image, and is constructed so that the plural toners at least include a black toner, and the abrading force of the black toner or its carrier therein acting on the photoreceptor surface is adjusted so as to be smaller than that of the other developing toners or their carrier therein. Since, in a tandem type color image forming apparatus, the developing devices, photoreceptors and toners for all colors will reach the end of their life at the same time, the image forming apparatus can be operated at low cost.
