The process cartridge (50) includes an image carrier (3) on which a toner image is formed; a cleaning unit (7) that cleans the image carrier (3) by removing residual toner remained after transferring the toner image formed on the image carrier (3) onto a transfer medium, which includes a cleaning member (70) that removes the toner from the image carrier (3) and a toner conveying unit that conveys the toner removed by the cleaning member (70) in a longitudinal direction of the cleaning member (70), including a toner conveying member (71) that makes a rotation to convey the toner removed by the cleaning member (70) in a predetermined direction and a rotary supporting member (74) that supports the toner conveying member (71) at a predetermined position such that the toner conveying member (71) can be rotated and makes a rotation with a driving force from outside; a side wall (53) for supporting the image carrier (3) such that the image carrier (3) can be rotated; and an outer cover member (51) having a surface parallel to the side wall (53). The side wall (53) includes a through hole (54). The rotary supporting member (74) includes a holding unit (52, 80) that passes through the through hole (54) and is held at the outer cover member (51) in a rotatable manner.
