摘要： An image forming device has a full-color image formation mode to form a color image using color photoconductor drums and a monochrome image formation mode to form a monochrome image using a photoconductor drum. In the image forming device, a driving unit drives rotation of an intermediate transfer belt or a transfer transport belt. A control unit changes rotational speeds of the color photoconductors in a transition from the full-color image formation mode to the monochrome image formation mode to make a torque to the driving unit in the full-color image formation mode equal to a torque to the driving unit in the monochrome image formation mode. A separator unit separates the color photoconductors from the intermediate transfer belt or the transfer transport belt after the rotational speeds of the color photoconductors are changed by the control unit.

摘要： In an image forming apparatus, a support frame is configured to support a plurality of photoconductors arranged in the apparatus, the support frame being allowed to be pulled out from a casing of the apparatus, and an intermediate transfer belt is disposed above the plurality of photoconductors and configured to be movable between a contact position in which the intermediate transfer belt is in contact with each of the plurality of photoconductors and a separate position in which the intermediate transfer belt is separate from the each of the plurality of photoconductors. A predetermined amount of upward movement of the support frame made when the intermediate transfer belt is or comes in the separate position renders the support frame operable to be pulled out in a direction of arrangement of the plurality of photoconductors.
