摘要： An image forming apparatus includes a fixing roller, a heating section, a pressurizing roller, an oil roller, a first cleaning roller, and a control section. The pressurizing roller is pressed against the fixing roller. The oil roller abuts against the fixing roller and is capable of being rotated by rotation of the fixing roller to apply oil onto a surface of the fixing roller. The first cleaning roller abuts against the oil roller and is capable of being rotated by rotation of the oil roller to clean a surface of the oil roller. When the control section determines that the fixing roller and the pressurizing roller have performed fixing on a predetermined number and more of consecutive sheet surfaces, the control section carries out a first control process which causes the heating section to stop and the fixing roller to rotate for a first predetermined time period after the fixing.

摘要： A cleaning device includes a cleaning web, a supply roller, a take-up roller, and a control section. Positioned in contact with a circumferential surface of a fuser roller, the web removes toner particles on the circumferential surface. The supply roller has the web wound thereon. The take-up roller takes up the web withdrawn from the supply roller. The control section controls rotation of the take-up roller. The control section performs a first process of causing the take-up roller to take up a first length of the web each time a predetermined taking-up condition is satisfied. The control section also performs a second process, instead of the first process, of causing the take-up roller to take up a second length of the web each time after a first predetermined number of the first processes are performed.

摘要： When an image forming apparatus, after a feeding error of a recording material occurs in a fixing device, re-forms on the recording material an image corresponding to image data which image was formed on a sheet which caused the feeding error, an image forming condition is caused to be different from an operation condition used when the feeding error has occurred. This makes it possible to prevent a JAM corresponding to the same image from recurring in the fixing device.
