Abstract
In a first paper-dust removing device, a brush is supported by a support member that is attached to the interior of a casing. The first paper-dust removing device mainly removes pulp fibers of the paper dust, and is located downstream from a transfer position in the photosensitive drum rotating direction. A second paper-dust removing device is additionally provided. The second paper-dust removing device includes a support member that is attached to a casing of a developing cartridge. The support member supports a non-woven fabric that is lined by a sponge. The second paper-dust removing device mainly removes talc in the paper dust. The second paper-dust removing device is located downstream from the first removing device in the photosensitive drum rotating direction. In the second device, the non-woven fabric is contacted with the photosensitive drum at substantially zero contact pressure.
