Claim:
An image forming apparatus comprising: an image forming section for forming an image on a recording material; a fixing device for conducting heat fixing of the image formed on the recording material; a control section for controlling a recording material conveyance speed and a warm-up completion temperature in the fixing device; a quick output mode setting section for setting a quick output mode by a user's operation to shorten a warm-up time for conducting image forming; and a recording material setting section for setting a type of the recording material; wherein the control section sets the recording material conveyance speed to be a first speed at a first warm-up completion temperature when the quick output mode is not set by the quick output mode setting section; wherein when the quick output mode is set, the control section sets the recording material conveyance speed to be a second speed, which is slower than the first speed, at a second warm-up completion temperature which is lower than the first warm-up completion temperature; and wherein the control section controls the warm-up completion temperature according to the type of the recording material set by the recording material setting section and the quick output mode setting section sets the quick output mode only when the recording material setting section sets a regular sheet.
