Image forming apparatus having drum supporting member and belt

The image forming apparatus as claimed in claim 2, wherein the pressing mechanism includes:na first link member that is extending in a moving direction, in which the moving member moves;a second link member that is extending in the moving direction and is disposed at a vertical level higher than the first link member, the second link member being provided with a plurality of second urging members in one to one correspondence with the photosensitive drums, each second urging member being configured to urge the corresponding photosensitive drum upward; anda plurality of joint members configured to couple the second link member to the first link member such that the second link member is movable between a first position and a second position different from the first position.

The image forming apparatus as claimed in claim 7,nwherein the drum supporting member has a first end and a second end in a pulled-out direction, in which the moving member is pulled out from the mounted position to the pulled-out position, the first end being defined as an upstream end of the drum supporting member in the pulled-out direction and the second end being defined as a downstream end of the drum supporting member in the pulled-out direction, the drum supporting member being configured so as to be mounted in and removed from the moving member by rotating the second end about the first end which is a fulcrum, andwherein the drum supporting member includes:a pair of side plates that face each other and that are apart from each other in an axial direction of the photosensitive drums, the pair of side plates rotatably supporting the photosensitive drums;a first protruding part that is provided at an upstream end of each side plate in the pulled-out direction and that protrudes in the axial direction; anda second protruding part that is provided at a downstream end of each side plate in the pulled-out direction and that protrudes in the axial direction; andwherein the moving member includes:a pair of side walls that face each other and that are apart from each other in the axial direction;a first engaging part that is provided at an upstream end of each side plate in the pulled-out direction and that is configured so as to be engaged with the first protruding part to position the first protruding part relative to the moving member while allowing rotation of the first protruding part; anda second engaging part that is provided at a downstream end of each side plate in the pulled-out direction and that is configured so as to be engaged with the second protruding part to allow rotation of the drum supporting member relative to the moving member.

The image forming apparatus as claimed in claim 9, wherein the moving member is provided with a handle that protrudes from the downstream-side wall of the moving member toward a downstream side in the pulled-out direction.

The image forming apparatus as claimed in claim 9, wherein the pair of side walls are disposed so as to face outer sides of the drum supporting member in the axial direction.

The image forming apparatus as claimed in claim 21, wherein each side wall is provided with a guide part that is configured to guide movement of the moving member relative to the main body.
