摘要： There is a multi-color copying apparatus having image processing functions which can easily designate arbitrary areas when the trimming or masking is executed. This apparatus comprises: an area designating device to designate the first area of the original; a first developing device to develop the image of the first area in the first color; a second developing device to develop the image of the second area in the second color; and a control circuit for making the first developing device operative without making the second developing device operative in accordance with the designation of the first area and, after completion of the development of the image of the first area, making the second developing device operative without making the first developing device operative. The control circuit inhibits the operation of the first or second developing device by moving the first or second developing device to a position away from the photo sensitive drum, or by applying the bias voltage to the first or second developing device such that the toner from the inoperative developing device is not deposited onto the drum.
