FIXING DEVICE AND IMAGE FORMING APPARATUS

摘要

A fixing device includes a cylindrical rotating member rotating in a circumferential direction thereof and having a slot at an end thereof and a protruding section extending along an edge of the slot at a front side in a rotational direction of the rotating member, the rotating member receiving a rotational driving force via the slot; a pressing member pressing a recording medium bearing an unfixed toner image on a surface thereof by nipping the recording medium together with the rotating member so as to fix the toner image onto the surface; a heat source heating the recording medium; and a driving member having an engagement section engaged with the slot and in contact with the protruding section at a position separated from a peripheral wall of the cylinder by a certain distance, the driving member imparting the rotational driving force to the rotating member via the engagement section.
