摘要： An image forming apparatus for forming image on a recording medium includes a photosensitive member, a motor, a belt, and a drive member to rotate the belt, the drive member including a driven coupling. The apparatus also includes a drive coupling to rotate by a driving force generated by the motor, the drive coupling being movable in an axial direction to take an engagement position at which the driving force is transmittable to the driven coupling, and a release position. The apparatus further includes a transfer member to transfer a toner image onto the recording medium or the belt, a voltage application unit to apply a voltage to the transfer member, and a control unit to cause the voltage application unit to apply the voltage to the transfer member after the drive coupling moves to the engagement position and the driving force is transmitted to the driven coupling.

摘要： An image forming apparatus is provided for forming an image on a recording material. An opening is provided to a main assembly of the image forming apparatus, with first and second openable members being movable between closed positions in which portions of the opening are closed and open positions in which portions of the opening are opened. A movable member is movable between a set position inside the main assembly and an outward position in which the movable member, having passed through the opening, is located at an outermost position. The movable member is capable of supporting a plurality of cartridges, side by side, with each of the cartridges including at least one of an image bearing member on which a latent image is to be formed and developing means for developing with a developer the latent image formed on the image bearing member.
