Abstract: A fixing device includes a fixing member, a pressuring member, a fixing frame, a supporting member and a biasing member. The fixing member and the pressuring member forms a fixing nip. The supporting member has a bearing part which rotatably supports the pressuring member. The biasing member biases the supporting member in a pressing direction in which the pressuring member is made to come into pressure contact with the fixing member. The supporting member has a fulcrum part and a contact part. The fulcrum part is disposed separately from the bearing part and turnably engaged with the fixing frame. The contact part is disposed on an opposite side to the fulcrum part with respect to the bearing part. The fixing frame has a restriction part. The restriction part comes into contact with the contact part to restrict the supporting member from being moved in the pressing direction.

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 move the lock lever in the opening direction of the cover by a biasing force of the elastic member and closing the dustproof shutter when the cover is unlocked.

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.
