The ratio in the axial direction of the photosensitive drum is varied by the lens drive

system, and the ratio in the peripheral direction of the photosensitive drum is varied by
the scanner drive system.

The lens drive system uses a zoom lens, and it varies the reproduction ratio in the

axial direction of the photosensitive drum by changing the lens position and the focal
distance.

The scanner drive system moves the No.1 mirror relatively faster (Reduce) or slower

(Enlarge) than the peripheral speed of the photosensitive drum, thereby varying the
peripheral reproduction ratio.
