Abstract
Official abstract text for this publication.
An intermediate transfer unit includes an intermediate transfer belt, a housing, a grip, and a cover. The housing supports a plurality of stretching rollers stretching the intermediate transfer belt and has a downstream plate in a pull-out direction of the intermediate transfer unit. The downstream plate is orthogonal to the pull-out direction. The grip is on the downstream plate. The cover covers the downstream plate and has a hole to access the grip.
First claim
Opening claim text (preview).
The invention claimed is: 1 . An intermediate transfer unit comprising: an intermediate transfer belt; a housing that supports a plurality of stretching rollers stretching the intermediate transfer belt, the housing having a downstream plate in a pull-out direction of the intermediate transfer unit, the downstream plate being orthogonal to the pull-out direction; a grip on the downstream plate; and a cover to cover the downstream plate, the cover having a hole to access the grip. 2 . The intermediate transfer unit according to claim 1 , further comprising a fastener fastening both ends of the downstream plate to a body of an image forming apparatus, wherein the cover has a fall prevention portion to prevent the fastener from falling when fastening of the downstream plate and the body of the image forming apparatus is released. 3 . The intermediate transfer unit according to claim 1 , further comprising a tensioner to apply tension to the intermediate transfer belt, wherein the tensioner is removable from the housing without removing the cover. 4 . The intermediate transfer unit according to claim 1 , further comprising: a detachable unit attachable to and detachable from the intermediate transfer unit; and an opening-and-closing member rotatable between a passage closing position for closing a passage in which the detachable unit is attached to and detached from the intermediate transfer belt and a passage opening position for opening the passage. 5 . The intermediate transfer unit according to claim 4 , further comprising a tensioner to apply tension to the intermediate transfer belt, wherein the tensioner includes a guide to guide attachment and detachment of the detachable unit to and from the intermediate transfer unit. 6 . An image forming apparatus comprising the intermediate transfer unit according to claim 1 .
