機時間表示装置。[Claims for Utility Model Registration] A fixing device that heats and fixes unfixed paper, heating means within the fixing device, first temperature detection means that detects the temperature of the fixing device, and any one of room temperature and internal atmosphere temperature. a second temperature detection means for detecting whether the fixing device reaches a usable temperature based on a detection signal from one of the first and second temperature detection means; In the image forming apparatus, the image forming apparatus includes a calculation means for calculating the waiting time until the end of the heating period, and a display means for displaying the waiting time, wherein the temperature detected by the first temperature detection means and a predetermined reference temperature are set at the time when heating of the fixing device is started. means for comparing and calculating the detected temperature, when the detected temperature is higher than the reference temperature, the waiting time based on the signal from the first temperature detecting means is displayed on the display means, and when the detected temperature is lower than the reference temperature, the waiting time is displayed on the display means. 2. A standby time display device for an image forming apparatus, characterized in that a standby time based on a signal from a temperature detection means is displayed on the display means.
