Abstract
Official abstract text for this publication.
In an image-forming device, a recovering unit removes waste developer material to be discarded from a target and collects the waste developer material. A waste developer material accommodating part is provided integrally with the developer material accommodating part and accommodates waste developer material collected by the recovering unit. A waste developer material conveying mechanism is connected to both of the recovering unit and the waste developer material accommodating part and conveys the waste developer material from the recovering unit to the waste developer material accommodating part. An urging member is interposed between the waste developer material accommodating part and the waste developer material conveying mechanism and urges a developing roller toward a photosensitive drum via a developer material accommodating part.
First claim
Opening claim text (preview).
What is claimed is: 1. An image-forming device, comprising: a photosensitive drum; a developer material accommodating part that is configured to accommodate developer material; a developing roller that is configured to supply the photosensitive drum with the developer material accommodated in the developer material accommodating part; a recovering unit that is configured to remove, from a target for waste developer material recovery, waste developer material to be discarded…
