    Abstract: A fixing apparatus includes a belt, a rotary member, a pad member, and a slide member. A distance in the conveyance direction between a first position and a second position is 3.0 mm or less. The first position is a downstream edge of a tip of a projection positioned most downstream in a direction of rotation of the belt. The second position is an upstream edge, in the direction of rotation of the belt, of the guide portion that contacts with the inner circumference surface of the belt. A distance in the pressing direction between a third position and a fourth position is 0.4 mm or more and 2.0 mm or less.

  • Patent number: 12111594
    Abstract: A fixing device includes a heating unit, a pressure unit, a first frame, an urging member, a support member, and a fixing member. The heating unit heats toner carried by a recording medium. The pressure unit pressurizes the heating unit to form a nip portion with the heating unit and fixes a toner image onto the recording medium at the nip portion with the heating unit. The first frame moves to a first position where the heating unit is exposed and moves to a second position where the heating unit is covered. The urging member urges the heating unit to position the heating unit. The support member supports one end of the urging member and the fixing member fixes the support member to the fixing device.
