PURPOSE:To easily set the operating value of a copying process, by causing a stored standard operating value to be displayed as '0' when mode is switched to a set mode. CONSTITUTION:When a start key 112a and ten keys 112d are operated in a prescribed procedure together with a main switch 13 and service switch 15, this electronic copying machine 10 is switched to an ordinary copy mode, service mode, or adjustment mode. When the mode is switched to a set mode, the 1st display means displays the standard operating value of each process stored in the 1st storing means as '0'. Therefore, when the developing capacity is to be improved, +30V is, for example, set and inputted and, when the capacity is to be dropped, -30v is for example, inputted even when a standard developing bias voltage is unknown at the time of adjustment of developing bias voltage. Therefore, the developing bias voltage is stored in the 2nd storing means as 330V or 270V and the operating value is used in an execution mode. |
