Abstract
A fixing device includes a fixing belt formed in a cylindrical shape, with a lubricant applied to an inner circumferential surface, and set such that a circumferential surface rotates in a circumferential direction, a heater retention member that retains the heater, inside of the fixing belt, and a pressure member that defines a nip region, through which a recording medium is transported in a nipped state, between the pressure member and a portion of the fixing belt heated from inside by the heater, and drives the fixing belt to rotate. The heater retention member includes a first opposing face extending in a rotation axis direction of the fixing belt, and opposed to the inner circumferential surface of the fixing belt. The first opposing face includes slits aligned in the rotation axis direction of the fixing belt, and a lubricant is applied in advance inside the slits.
