Abstract
An image forming apparatus capable of performing an image forming operation together with temperature rise by heating of a fixing apparatus to ensure a good fixability and a shortest first print out time and to prevent loss of power consumption without burdening a constitutional member of the image forming apparatus (e.g., life-shortening of the constitutional member) is provided. The image forming apparatus includes a fixing apparatus for heat-fixing a toner image on a recording material and a detection member for detecting a toner of a fixing apparatus member and performs simultaneously temperature rise by heating of the fixing apparatus and an image forming operation including a pre-process and an image forming sequence. In the image forming apparatus, a start temperature of the pre-process and a start temperature of the image forming sequence with respect to the fixing apparatus member are made variable depending on whether full-color image formation is performed or mono-color image formation is performed.
