Abstract
The image forming apparatus, in the case where image forming is performed on a recording medium whose size covers a position of a second temperature detection element perpendicularly disposed to the recording medium conveyance direction, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a first power supply control is switched to a second power supply control. In the case where image forming is performed on a recording medium whose size does not cover a position of the second temperature detection element, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a conveyance control portion executes a control for extending the conveyance interval of the recording medium. Thus, an unduly large temperature rise in the non-sheet passing portion is prevented, and a good quality image can be provided without glossy unevenness in one sheet.
