摘要： In a fixing device, a belt moves in a predetermined direction to heat and melt a toner image on a recording medium. A pressing rotary member is pressed against the belt to form a nip portion to nip and convey the recording medium bearing the toner image. A heating member is fixedly provided inside a loop formed by the belt and faces an inner circumferential surface of the belt. The heating member is heated by a heater to heat the belt. The heating member includes a primary heating portion directly heated by the heater, and a secondary heating portion heated by heat conducted from the primary heating portion. The primary heating portion and the secondary heating portion are provided in a circumferential direction of the heating member. The secondary heating portion has a heat capacity smaller than a heat capacity of the primary heating portion.
