ABSTRACT:
A copying machine which can operate in a mode newly selected by an operator, without the necessity of changing the copying conditions set at the start of the copying process, and which can also operate in the mode initially selected by the operator as soon as the operator selects the initial mode again. The copying machine can be set in a high-speed copying mode after it has produced the first hard copy, if the image being copied is formed of characters only, thereby to produce other copies at high speed. The other copies are produced without a break, thus reducing the amount of toner and paper, and also the copying time, to a minimum. This helps decrease the copying costs.
