  • Patent number: 9594341
    Abstract: An image forming apparatus includes a main assembly including an opening, a cartridge tray for dismountably supporting a cartridge, an openable member for opening and closing the opening, with the cartridge tray being provided at one end portion side, and a limiting member. An urging member urges the cartridge tray from an inner position in the main assembly to an outer position, and a locking member moves between a regulating position and a non-regulating position in interrelation with movement of the openable member. When the openable member is closed, the locking member moves to the regulating position at which the locking member engages with the cartridge tray to push it to the inner position and limits movement of the cartridge tray toward the outer position, and when the openable member is opened, the locking member moves to the non-regulating position at which the locking member disengages from the cartridge tray.

  • Publication number: 20150168911
    Abstract: An image forming apparatus includes an opening and a door; a tray for supporting a cartridge, the tray being movable between outer and inner positions; a stopper movable in the inner position between a limiting position in which the tray is limited by an engaging portion and a release position; an urging member, upstream of the stopper, for urging the tray to the outer position, the urging member providing a rotational force to the tray to project the other end beyond the one end, when the stopper is in the limiting position; and a locking member interrelated with the door. When the door is closed, the locking member engages with the other end of the tray to push the tray to the inner position and limits downstream movement of the tray toward the outer position. When the door is opened, the locking member disengages from the tray.

  • Patent number: 8532532
    Abstract: 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.
