Image forming apparatus incorporating therein a fixing unit capable of cleaning a fixing roller by means of an oil roller and a cleaning roller
Abstract:
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.
