摘要： 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.

摘要： The sponge sealing member of the side seal is arranged on the roller opposed face of the seal arrangement portion so that the lower end face at the upstream side in the rotative direction of the developing roller is positioned to have the same face as the back end face of the seal arrangement portion and the upper end face at the downstream side is connected with the lower end face of the side portion of the blade back seal. The felt sealing member is arranged so that the upper end portion at the downstream side in the rotative direction of the developing roller is formed astride the lower end portion of the leaf spring member and the sponge sealing member, extends along the sponge sealing member, runs through the back end face of the seal arrangement portion and runs round to the lower face of the seal arrangement portion.
