Abstract
A fixing device includes a rotatable member having an electroconductive layer; a magnetic member which does not form a loop outside the electroconductive layer; a coil helically wound outside said magnetic member, wherein the coil forms an AC magnetic field by a flow of a current therethrough to cause the electroconductive layer to generate heat through electromagnetic induction heating; and a back-up member. When a circumferential direction resistance R of the electroconductive layer is represented by the following formula (1), a frequency f of the AC magnetic field and the circumferential direction resistance R satisfy the following formula (2):=ρ×2π  (1)≧15 (kHz/milliohm)  (2)
