Abstract:
1. A fixing apparatus, comprising: a pair of fixing rollers, a fixing roller drive source for rotationally driving the fixing rollers, a paper separation member arranged so as to be capable of contacting and separating from a surface of one of the fixing rollers in order to separate from the fixing roller a paper transported along with rotation of the fixing roller while contacting the surface of the fixing roller, a separation member drive source for driving the paper separation member, and a control portion for controlling a fixing process, wherein the control portion performs control so that the paper separation member separates from a surface of the fixing roller by performing drive control on the separation member drive source before a change in a drive state of the fixing rollers by the fixing roller drive source, and the paper separation member contacts the surface of the fixing roller by performing drive control on the separation member drive source after a change in the drive state of the fixing rollers by the fixing roller drive source, and further comprising: a temperature detection portion for detecting a temperature of the surface of the fixing roller, and a heating portion for heating the fixing roller, wherein the control portion executes temperature control on the fixing roller using the heating portion based on a temperature detected by the temperature detection portion in a period in which the paper separation member is in contact with the fixing roller, and carries out separation control of the paper separation member during execution of this temperature control, and the control portion causes the paper separation member to separate from the surface of the fixing roller before stopping of rotation of the fixing roller, and causes the paper separation member to contact the surface of the fixing roller after stopping of rotation of the fixing roller.
