An image forming apparatus, such as a printer, includes an image forming unit forming a toner image on an image carrier, a transfer unit for transferring the toner image onto a recording medium, a pair of a fusing rotating body and a pressure rotating body, a fusing unit for fusing the toner image on the recording medium, a temperature detecting unit for detecting the temperature on the surface of the fusing rotating body, and a control unit. An amount of decrease in the temperature of the fusing rotating body surface is measured at a predetermined time, and the time between an image formation request and the arrival of the recording medium, with the toner image formed thereon, at a fusing/nipping portion formed between the fusing rotating body and the pressure rotating body is extended when the temperature decrease amount is greater than a threshold value. |
