Then, the clutch is engaged and the belt (1) driven for developing the electrostatic image into a toner image and transferring and fixing the toner image to a copy sheet. The motor (3) also drives a pulse generator (18) which produces timing pulses. The timing pulses are counted by a counter. A control unit (E19) such as a microcomputer (19) controls the operation of the apparatus in accordance with predetermined counts in the counter. Marks (15.sub.1), (15.sub.2) are provided on the belt (1) in spaced relation.
