Abstract
Disclosed is an extremely convenient copying machine for performing copying operations using a selected color toner of internally provided color toner developer containers, which copying machine effectively provides means for cumulatively counting the number of copied papers processed by each color toner developer container. The preferred embodiment provides a plurality of counters for counting the number of copied papers provided for each color toner developer container, and feeds the counter pulses generated in each copying cycle to these counters according to the selected color of the internally installed color toner developer containers. A display unit is also provided so that the actual number of copied papers processed by each color toner developer container can be cumulatively displayed as required.
