A cleaning device includes: a first shaft; a cleaning roller which is operable to come into contact with a surface of a photosensitive drum, and is integrally rotated with the first shaft; a pressing member for pressing the cleaning roller against the surface of the photosensitive drum; a second shaft; a spiral roller which is integrally rotated with the second shaft, and is operative to collect toner residues from the surface of the photosensitive drum; a driving force transmitting mechanism for transmitting a driving force of the photosensitive drum to the first shaft and the second shaft; and a pair of arm members which are pivotally interlocked with the second shaft, and are pivotally interlocked with the first shaft. The cleaning device allows for suppressing image jitter or noise resulting from jitter of the photosensitive drum.
