Abstract:
An image forming apparatus includes: a belt conveyance device that corrects leaning of an endless belt member, the belt conveyance device being detachably attachable to an apparatus body of the image forming apparatus; a first guiding portion that supports a first guided portion provided in a frame member supporting rotatably a first roller on which the belt member is laid under tension and guides the belt conveyance device attached to or detached from the apparatus body; and a second guiding portion that supports a second guided portion provided in a steering unit supporting rotatably a second roller on which the belt member is laid under tension, releases the second guided portion at an attachment position of the belt conveyance device to the apparatus body, and guides the belt conveyance device attached to or detached from the apparatus body.

Claim (Index 1):
An image forming apparatus comprising:\n an apparatus body; and a belt conveyance device that is detachably attached to the apparatus body, wherein the belt conveyance device has: a first roller configured to support an endless belt member; a frame member that supports rotatably said first roller; a second roller configured to support an endless belt member; a steering unit that supports rotatably said second roller, the steering unit being supported to be tiltable with respect to the frame member around an axial line vertical to an axial line of the second roller; a sliding member provided in a state where rotation is restricted at both end portions of the second roller; wherein when the belt member moves to one axial end side of the second roller, the steering unit tilts with respect to the frame member in a direction that the belt moves to the other axial end side of the second roller by a force generating by contacting the belt and the sliding member a first guiding portion that is provided in the apparatus body to support a first guided portion provided in the frame member and guide the belt conveyance device attached to or detached from the apparatus body; and a second guiding portion that is provided in the apparatus body to support a second guided portion provided in the steering unit, release the second guided portion at an attachment position of the belt conveyance device to the apparatus body, and guide the belt conveyance device attached to or detached from the apparatus body.
