| 20090060561 | IMAGE FORMING APPARATUS - An image forming apparatus is provided with a feed interval control section that sets feed intervals of the recording materials, for a defined period from immediately after completion of the warm-up operation for a fixing-side rotor and the pressure-side rotor determined by a warm-up completion determination section, to be longer than feed intervals of the recording materials posterior to the defined period in a high-humidity and low-temperature state. Thereby, the image forming apparatus prevents elongation of a warm-up time while achieving both reduction of the back curl and maintenance of fixability in the high-humidity and low-temperature state. | 03-05-2009 |
