Abstract:
A fixing device for fixing a toner image carried on a recording medium on said recording medium, said fixing device comprising:a heating member; a pressing member facing said heating member; a coating member configured to coat a parting agent on said heating member; and agent feeding means intermittently brought into contact with said coating member for feeding the parting agent; wherein assuming that a distance between a nip between said agent feeding means and said coating member, as measured in a direction of forward rotation of said coating member, is A, that a distance between a nip between said coating member and said heating member and a nip between said heating member and said pressing member, as measured in a direction of forward rotation of said heating member, is B, and that a circumferential length of said heating member is C, then a period of time T in which the recording medium enters said nip between said heating member and said pressing member satisfies a relation: A+B+C/linear velocity of image formation&lE;T.
