    摘要： A nip formation member is configured to be disposed inside a loop of a rotatable belt. The nip formation member includes a base, a thermal equalizer, an attachment, and a fastener. The base has a bottomed fastening hole. The thermal equalizer is configured to face the belt and a surface of the base not having the bottomed fastening hole. The thermal equalizer has a higher thermal conductivity than the base. The attachment has a fastening hole and face another surface of the base having the bottomed fastening hole. The attachment is configured to fix and position the base and the thermal equalizer. The fastener is fastened to the bottomed fastening hole of the base through the fastening hole of the attachment from the attachment.

    摘要： A fixing device includes a belt, an opposed rotator, a nip formation pad, a heater, a stay, and a positioner. The nip formation pad has a plurality of projections in a longitudinal direction of the nip formation pad. The positioner is disposed between the nip formation pad and the stay to position the nip formation pad. The positioner has a plurality of insertion holes arranged in a longitudinal direction of the positioner to accept the projections and restrict movement of the nip formation pad with respect to the positioner in a rotation direction of the belt and a direction opposite the rotation direction. The plurality of insertion holes includes an insertion hole disposed at a position corresponding to an end portion of the nip formation pad to accept two or more projections of the projections arranged in the longitudinal direction of the nip formation pad.

    摘要： A fixing unit includes an endless belt unit accommodating a heat source, a pressure roller to rotate in contact with the fixing belt unit forming a pressure border therebetween, and a heat transfer member heated by the heat source to heat the fixing belt unit. The heat transfer member is secured inside an inner circumferential surface of the fixing belt unit and supports the fixing belt unit. A fixed member is secured inside the inner circumferential surface of the fixing belt unit and is pressed against the pressure roller via the fixing belt unit. The heat transfer member has at least one convex portion partially formed in an outer circumferential surface of the heat transfer member in a rotational direction of the fixing belt unit and a longitudinal direction of the heat transfer member to narrow a gap formed between the heat transfer member and the fixing belt unit.
