FIXING APPARATUS AND IMAGE FORMING APPARATUS EQUIPPED WITH THE FIXING APPARATUS

摘要

PROBLEM TO BE SOLVED: To prolong the life of a fixation body of an oilless type fixing appara tus and to shorten the warm-up time while securing excellent fixing perfor mance. SOLUTION: The fixing roller 1 has its outer periphery formed by providing a releasing layer 22 on a rigid core bar 21 and satisfies a relation of 10.0×105>=F/S>=2.0×105, where F [N] is the press-contact force acting between a fixing roller 1 and a pressure roller 2 and S [m2] is the area of the nip part formed by the fixing roller 1 and the pressure roller 2.
