Abstract

PURPOSE:To shorten the unusable period and to cope with an emergent demand for use, by detecting the temperature of a fixing device and realizing the copying number of sheets corresponding to the detected temperature. CONSTITUTION:A temperature detecting element 1 such as a thermistor, etc. detects the temperature of a heating roller, and the detection signal is applied to a CPU4 via an interface 3 after an A/D conversion 2. The CPU4 compares the stored set temperature with an input signal and thus calculates the number of sheets that can be copied to display the number at a display element 6. This output signal is distributed also to a controller 7, and the controller 7 controls continuously a copier in an operable state until the display shows O sheet.
