    摘要： The present invention relates to a process cartridge removably mountable on an image forming apparatus comprising a support, a rotary member having an image bearing surface and rotatably supported by the support, and a rotatable developing roller supported by the support, for carrying developer thereon and supplying the developer to the image bearing surface to develop a latent image formed on the image bearing surface. A first gear is arranged coaxial with the rotary member, a second gear is arranged coaxial with the developing roller and meshed with the first gear, and a guide means is provided for guiding the developing roller in a direction toward and away from the rotary member. The direction in which the developing roller is guided by the guide means is inclined with respect to a straight line connecting the center of rotation of the rotary member to the center of rotation of the developing roller, by an angle between 0.7.times..THETA. (.THETA. is a pressure angle of the second gear) and 1.3.times..THETA.. The cartridge further includes a bias means for biasing the developing roller toward the image bearing surface.

    摘要： An image forming apparatus having an intermediate guide device which is disposed at an intermediate portion between a transfer section and a fixing section for the purpose of guiding a transfer medium while imparting breadthwise tension thereto. This intermediate guide device prevents any wrinkle occurring in the transfer medium near the fixing section from being moved toward the transfer section. In addition, the toner on the transfer medium is prevented from being transferred onto upper-surface rollers of the guide device when the electric charge of the toner leaks to the rollers.
