第１項に記載のトナー不足警告装置。[Claims for Utility Model Registration] 1. Toner amount detection means for detecting the amount of toner in the developing device, and calculating the number of copies that can be made until the toner in the developing device runs out based on a signal from the toner amount detecting device. 1. A toner shortage warning device comprising: a control means for activating a warning means when a set number of copies is greater than the number of possible copies. 2. Utility model registration claim 1, characterized in that the control means is controlled so that when the set number of copies is greater than the number of copies that can be made, the warning means is activated and the copying operation is disabled. The toner shortage warning device described in section.
