An image forming apparatus has an image forming unit, a sheet supplying unit, a register roller, and a paper particle removing unit which includes a paper particle removing roller arranged to face the register roller and configured to collect paper particles on the sheet which is nipped between the register roller and the paper particle removing roller, a paper particle container configured such that the paper particles removed by the paper particle removing roller are accumulated therein, and an auger arranged inside the paper particle container. The paper particle removing roller, the paper particle container and the auger of the paper particle removing unit are configured to move together between a contact position where the paper particle removing roller contacts the register roller and a spaced position where the paper particle removing roller is spaced from the register roller. |

1. An image forming apparatus, comprising:
an image forming unit configured to form an image on a sheet; a sheet supplying unit configured to supply a sheet to the image forming unit; a register roller arranged downstream, in a sheet feeding direction, of the sheet supplying unit and upstream, in the sheet feeding direction, of the image forming unit; a paper particle removing unit includes:
a paper particle removing roller arranged to face the register roller and configured to collect paper particles on the sheet which is nipped between the register roller and the paper particle removing roller;a paper particle container configured such that the paper particles removed by the paper particle removing roller are accumulated in the paper particle container, the paper particle container having a first guide configured to guide the sheet toward the register roller; andan auger arranged inside the paper particle container; a second guide arranged to face the first guide, wherein the second guide, in association with the first guide, defines a sheet feed path; a frame configured to support the register roller and the paper particle removing roller; and a cover configured to pivot between an open position and a closed position, the cover being separate from the frame, wherein the paper particle removing roller, the paper particle container and the auger included in the paper particle removing unit are configured to be movable together between a contact position where the paper particle removing roller contacts the register roller and a spaced position where the paper particle removing roller is spaced from the register roller, wherein the paper particle container further includes
a contact portion projecting toward the second guide and configured to contact the second guide;an upstream side wall arranged on an upstream side, in a direction where the sheet is fed as guided by the first guide;a front wall; andcontact parts provided to both ends, in a width direction, of the front wall, the contact parts being arranged on an upstream side, in the direction where the sheet is fed, with respect to the front wall, and wherein the paper particle removing unit is configured to rotate about the contact portion, the paper particle removing unit being movable between the contact position and the spaced position as it rotates about the contact portion. |
