Abstract: An image forming apparatus includes a toner case, an apparatus main body and a cover. The toner case includes a case main body, a shutter and a manipulation portion. The case main body has a discharge port configured to discharge a toner. The shutter opens/closes the discharge port. The manipulation portion is movable between a first position to make the shutter open the discharge port and a second position to make the shutter close the discharge port. To the apparatus main body, the toner case is detachably attached. The cover is openably/closably attached to the apparatus main body. The cover includes an interfering member. The interfering member is movable between an interfering position where the interfering member interferes with the manipulation portion being in the second position and an interference release position where the interfering member does not interfere with the manipulation portion being in the second position.

Abstract: An image forming apparatus includes a cover and a locking mechanism. The locking mechanism restricts a turning of the cover from a closed position. The locking mechanism has a first locking member, a second locking member and a lever member. The first locking member and the second locking member are movable between a lock position where they engage with the apparatus main body and an unlock position where they disengage with the apparatus main body. The lever member moves the first locking member and the second locking member between the lock position and the unlock position. An engagement quantity of the first locking member with the apparatus main body is larger than that of the second locking member at the lock position. The first locking member is formed with an engaging piece which is turnable by turning of the cover in an opening direction at the unlock position.

Abstract: An image forming apparatus includes a dustproof shutter, a lock lever, a shutter lever and an elastic member. The dustproof shutter is openably/closably supported in a case so as to protect an exposure device. The lock lever is configured to lock a cover openably/closably provided in the case, and to be movable in an opening direction of the cover. The shutter lever is provided at a position coming into contact with the lock lever and the dustproof shutter when the cover is closed. The elastic member biases the shutter lever toward the lock lever. The shutter lever moves between a first position to open the dustproof shutter when the cover is locked and a second position to close the dustproof shutter when the cover is unlocked by moving the lock lever in the opening direction of the cover with assistance from a biasing force of the elastic member.
