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.
