Abstract

PURPOSE:To change a number of rotation for cleaning in an electrophotographic copying machine controlled with a microcomputer, by using a control program changeable with a switch. CONSTITUTION:A control circuit comprises a driving circuit 42 for driving each part of an image-forming apparatus with an output of a microcomputer muCOM41, a pulse-generating unit 11b for producing drum clock pulses DCK, and a potential setting unit 43 having a switch SW connected with the input port of muCOM41. When the switch SW is turned on, an input signal CM becomes a low level state and when off, a high level state.
