Process cartridge, image forming apparatus and intermediate transfer belt

摘要

A process cartridge which integrally supports therein a cylindrical latent-image-bearing member on which a toner image is formed and an intermediate transfer belt to which the toner image is primarily transferred and from which it is secondarily transported to a transfer medium. To prevent the photosensitive member from being unwantedly triboelectrically charged during transportation, the cartridge satisfies any of requirements that A) the latent-image-bearing member has a surface potential Vt of -200 V<=Vt<=200 V when the intermediate transfer belt and the photosensitive member are rubbed with each other, B) a spacer member is provided between the intermediate transfer belt and the latent-image-bearing member, and the photosensitive member has a surface potential Vt of -200 V<=Vt<=200 V when the former and the latter are rubbed with each other, and C) the cartridge has a means for lowering contact pressure of the intermediate transfer belt against the latent-image-bearing member.
