摘要： A process is disclosed producing an intermediate transfer member used in an image-forming apparatus in which an image formed on a first image-bearing member is transferred to a second image-bearing member. The process has the steps of melt-extruding an extrusion material from a circular die by means of an extruder and thereafter making the same into a desired shape to obtain a cylindrical extruded product, and forming the resultant cylindrical extruded product into the intermediate transfer member. The cylindrical extruded product contains a thermoplastic resin and an ion-conductive resistance control agent, and a ratio of the diameter of the intermediate transfer member obtained to the die diameter of the circular die is from 0.5 to 4.0. Also disclosed are an intermediate transfer member obtained by the production process, and an intermediate transfer member having the intermediate transfer member.

摘要： A process cartridge 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 latent-image-bearing 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 latent-image-bearing 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 latent-image-bearing 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 device for lowering contact pressure of the intermediate transfer belt against the latent-image-bearing member.
