发明名称 Image-forming device having photosensitive drums, endless belt, and recovering unit
摘要 In an image-forming device, photosensitive drums are held by the holding member. Developer material accommodating parts are held by the holding member to form a row of developer material accommodating parts in a prescribed direction. An endless belt extends in the prescribed direction. A recovering unit removes, from the belt, waste developer material and collects the waste developer material. A waste developer material conveying mechanism conveys the waste developer material from the recovering unit to a waste developer material accommodating part. The waste developer material accommodating part is disposed on an upstream side of a most upstream developer material accommodating part in the row of the developer material accommodating parts in the prescribed direction, and accommodates the waste developer material.

主权项 1. An image-forming device, comprising: a holding member; a plurality of photosensitive drums that are held by the holding member, that are juxtaposed with one another in a prescribed direction, and that are arranged spaced apart from one another to form a row of photosensitive drums in the prescribed direction; an intermediate transfer belt extending in the prescribed direction and configured to contact all of the plurality of photosensitive drums at the same time, the intermediate transfer belt being configured to receive images of developer material transferred from the photosensitive drums; a secondary transfer roller configured to transfer the images of developer material from the intermediate transfer belt onto a sheet; a plurality of developer material accommodating parts that are held by the holding member in one to one correspondence with the plurality of photosensitive drums so as to form a row of developer material accommodating parts in the prescribed direction and that are configured to accommodate developer material to be supplied to the photosensitive drums, the developer material accommodating parts including a most upstream developer material accommodating part that is located at a most upstream end of the row of developer material accommodating parts in an intermediate-transfer-belt moving direction, the intermediate-transfer-belt moving direction being defined as a direction, in which portions of the intermediate transfer belt that are in contact with the plurality of photosensitive drums move, the intermediate-transfer-belt moving direction being parallel to the prescribed direction; a recovering unit that is configured to remove, from the intermediate transfer belt, waste developer material to be discarded from the intermediate transfer belt and collect the waste developer material; a waste developer material accommodating part that is configured to accommodate waste developer material collected by the recovering unit; and a waste developer material conveying mechanism that is configured to be connected to both of the recovering unit and the waste developer material accommodating part and to convey the waste developer material from the recovering unit to the waste developer material accommodating part, the waste developer material accommodating part being disposed at a downstream side of the secondary transfer roller and at an upstream side of the most upstream developer material accommodating part in the intermediate-transfer-belt moving direction such that the waste developer material accommodating part overlaps the row of developer material accommodating parts when viewed in the intermediate-transfer-belt moving direction, wherein the waste developer material conveying mechanism includes: a first conveying member that is configured to receive, from the recovering unit, waste developer material collected by the recovering unit and to convey the waste developer material inwardly along an axial direction of the photosensitive drums; anda second conveying member that is configured to receive waste developer material from the first conveying member and to convey the waste developer material to the waste developer material accommodating part, wherein the second conveying member is connected to a center of the first conveying member with respect to the axial direction.
