    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.

    摘要： An image forming apparatus includes a first image-bearing member, latent image-forming unit for forming an electrostatic latent image on the first image-bearing member, developer for developing the electrostatic latent image with a toner to form a toner image, an intermediate transfer member for receiving the toner image by primary transfer and transferring the toner image onto a second image-bearing member by secondary transfer, a charging member for charging a residual toner remaining on the intermediate transfer member after the secondary transfer, and a recovery member for recovering the charged residual toner at a recovery position by voltage application. The intermediate transfer member exhibits a charging characteristic such that it has a surface potential of at most 500 volts as an absolute value at the recovery position. The intermediate transfer member having such a charging characteristic is effective in suppressing an occurrence of electric discharge at the recovery position of the residual toner to provide an excellent cleaning performance.

    摘要： An intermediate transfer member is formed by at least a base layer and a surface layer. The base layer is formed by epichlorohydrin rubber and acrylonitrile-butadiene rubber mixed in a certain weight ratio (preferably 1:9 to 9:1). The surface layer is formed by urethane resin or elastomer and a fluorine-containing compound powder. The fluorine-containing compound powder may preferably be contained in an amount of 20-80 wt. % based on the surface layer. The intermediate transfer member is suitable for full-color image formation by electrophotography and is effective in improving a transfer performance and providing clear images without causing transfer failure even in repetitive use for a long period.

    摘要： An image forming apparatus includes: a first image-bearing member, an intermediate transfer member for receiving an image formed on the first image-bearing member and transferring the image onto a second image-bearing member, pattern-forming means for forming a prescribed pattern on the intermediate transfer member, density detection means for detecting a density of the pattern, and control means for controlling image forming conditions based on the detected density. The intermediate transfer member is set to have a reflectance of 10-70% for light having a wavelength in the range of 700-1500 nm at least in a region thereof for forming the prescribed pattern. As a result, the pattern density detection is suitably performed on the intermediate transfer member for all of yellow, magenta cyan and black, and the detected density data is used for controlling the image forming conditions.
