摘要： A belt device includes a belt wound around a plurality of rollers, one of the plurality of rollers, and a belt contact member disposed on the one of the plurality of rollers. The belt rotates along with the plurality of rollers. The belt contact member faces an edge of the belt in an axial direction of the one of the plurality of rollers and includes a flat portion and a separation portion. The flat portion forms a plane perpendicular to the axial direction of the one of the plurality of rollers. The separation portion is disposed outboard of the flat portion in a radial direction of the one of the plurality of rollers and has a surface located farther from the edge of the belt than the flat portion in the axial direction of the one of the plurality of rollers.

摘要： A charging device includes a charging roller, a drive transmission device, and a charging roller cleaner. The charging roller opposes an image carrier driven to rotate and rotates to charge the image carrier. The charging roller cleaner contacts the charging roller to clean the charging roller. The drive transmission device transmits torque from the image carrier to the charging roller, and includes an image carrier gear and a driven gear. The image carrier gear and the driven gear form a gear train to drive the charging roller in response to rotation of the image carrier. The charging roller cleaner is disposed facing a rear surface of the charging roller to prevent displacement of the charging roller due to a force generated by a pressure angle formed between the image carrier gear and the driven gear when the charging roller rotates in response to rotation of the image carrier.
