Zusammenfassung:The density of a toner in a developing device is detected by a magnetic sensor if the density is lower than a reference value, a toner-empty state is indicated on a control panel. When a copy key is operated in this toner-empty state, the number of copies in the toner-empty state is counted by means of a counter. If the count value is not larger than a preset value, the copying operation is allowed. If the count value exceeds the predetermined value, the copying operation is prohibited.
