  • Patent number: 9921543
    Abstract: An image-forming apparatus includes: a housing formed with an opening part; and a process cartridge detachably attachable to the housing through the opening part in a first direction. The housing includes a first support part arranged at the opening part, and a cover movable between a closed position and an opened position. The cover includes a second support part positioned away from the first support part in the first direction when the cover is at the opened position. The process cartridge includes: a drum cartridge having a drum frame; and a toner cartridge detachably attachable to the drum frame. When the cover is at the opened position, the first support part and the second support part are configured to support the drum frame of the process cartridge detached from the housing to restrict displacement of the drum frame in the first direction.

  • Patent number: 9557707
    Abstract: An image forming apparatus including a housing, a cover, an interlock switch, a locking assembly, and a biasing assembly. The housing may comprise a pair of frames spaced apart from each other, and may form an opening between the pair of frames. The cover may move between a covered position wherein the opening is covered and an opened position wherein the opening is uncovered. The interlock switch may be pressed by the cover when the cover is in the covered position. The locking assembly may move between a locking state wherein the locking assembly locks the cover in the covered position and a released state wherein the locking assembly allows the cover to move. Further, the biasing assembly may be positioned in or on at least one of the frames, and may bias the cover toward the opened position when the cover is in the covered position.
