摘要： A fixing device includes a fixing rotator, a pressure rotator, a cleaner, and a moving assembly. The cleaner contacts and cleans a cleaning target, which includes one of the fixing rotator and the pressure rotator. The moving assembly moves the cleaner between a contact position at which the cleaner contacts the cleaning target and a separate position at which the cleaner is apart from the cleaning target. The moving assembly includes a biasing member that presses the cleaner to move to the contact position. The moving assembly moves the cleaner from the contact position to the separate position against a biasing force of the biasing member. The moving assembly moves the cleaner from the separate position to the contact position while increasing and then decreasing the biasing force of the biasing member greater than the biasing force applied when the cleaner is located at the contact position.

摘要： A heating device includes a rotator, a heater, a heater holder, and a first high thermal conduction member. The heater includes a base and a plurality of heat generators being arranged on the base and including neighboring heat generators. The heater has a gap area between the neighboring heat generators. The first high thermal conduction member has a higher thermal conductivity than the base and faces the gap area.

摘要： A fixing device includes a fixing belt and a pressure rotator that presses against a nip formation pad via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt. A first holder holds a first lateral end of the fixing belt in an axial direction thereof. A second holder holds a second lateral end of the fixing belt in the axial direction thereof. The second holder, together with the first holder, defines a holder interval provided between the first holder and the second holder in the axial direction of the fixing belt. A lubricant supplying sheet impregnated with a lubricant is sandwiched between the nip formation pad and the fixing belt at the fixing nip. The lubricant supplying sheet has a sheet span in the axial direction of the fixing belt. The sheet span is within the holder interval.
