Abstract:
1. A transfer device provided for an image forming apparatus designed such that toner images formed on a plurality of image bearing members are transferred one over another on a transfer body disposed in contact with each of the image bearing members with predetermined pressure and thus a toner image in two or more colors is formed on the transfer body, the transfer device comprising: a first pressure varying mechanism configured to move a first transfer unit away from a first image bearing member of the plurality of image bearing members so as to separate the transfer body from the first image bearing member, wherein the first transfer unit is arranged on an opposite side of the transfer body from the first image bearing member; a second pressure varying mechanism configured to vary a transfer pressure between a second image bearing member of the plurality of image bearing members and the transfer body via a second transfer unit, wherein the second transfer unit is arranged on an opposite side of the transfer body from the second image bearing member; and a transmission member that mechanically links the first pressure varying mechanism and the second pressure varying mechanism such that the second pressure varying mechanism increases the transfer pressure between the second image bearing member and the transfer body when the first pressure varying mechanism moves the first transfer unit away from the first image bearing member.
