Image forming apparatus having cleaning unit including waste developer box

摘要

An image forming apparatus includes: an image forming unit including a plurality of photoconductor drums arranged in tandem; a conveyor belt arranged opposite to the photoconductor drums and configured to convey a recording sheet; and a cleaning unit including a cleaning member positioned in contact with the conveyor belt and configured to collect substance adhering to the conveyor belt, and a receptacle configured to store the substance collected by the cleaning member. The cleaning member is arranged on the same side as the image forming unit with respect to the conveyor belt and upstream from the image forming unit as viewed in a sheet conveyance direction along which the recording sheet is conveyed on the conveyor belt, and the image forming unit and the cleaning unit are pulled out together from a main body of the image forming apparatus toward an upstream side of the sheet conveyance direction.

主权项

1. An image forming apparatus comprising:
a photoconductor unit which comprises a first photoconductor configured to rotate about a first axis, a second photoconductor configured to rotate about a second axis parallel to the first axis, and a frame configured to support the first photoconductor and the second photoconductor and to be movable between a first position in which the frame is positioned outside a main body of the image forming apparatus and a second position in which the frame is positioned within the main body of the image forming apparatus; a belt disposed to face the first photoconductor and the second photoconductor and configured to convey a sheet; a first developer cartridge configured to store developer to be supplied to the first photoconductor; a second developer cartridge configured to store developer to be supplied to the second photoconductor; and a cleaning unit which comprises a waste developer box configured to store waste developer, and first and second carrying members configured to carry the waste developer to the waste developer box, the first carrying member being configured to carry the waste developer in a first direction in which the first axis extends, and the second carrying member being configured to carry the waste developer in a second direction orthogonal to the first direction, wherein the waste developer box is disposed on the same side as the first developer cartridge and the second developer cartridge with respect to the belt, wherein the first developer cartridge, the second developer cartridge, and the waste developer box are arranged along a sheet conveyance direction in which the sheet is conveyed on the belt, and wherein the frame supports the first carrying member and the second carrying member.
