摘要： In a fixing device, a first roller and a first fixing member are provided inside a loop formed by a first belt. A pressing member is pressed against the first roller and the first fixing member via the first belt. The first roller includes at least two enlarged radius portions of enlarged radius arranged axially along the first roller, at least one reduced radius portion of reduced radius sandwiched between the adjacent two enlarged radius portions in an axial direction of the first roller, and a concave portion formed by the reduced radius portion and the adjacent two enlarged radius portions sandwiching the reduced radius portion. The first fixing member is interdigitated with the first roller with play between the first fixing member and the first roller.

摘要： A fixing device includes a fuser member, a stripper member, an endless rotary belt, a heater, a pressure member, and a belt cooler. The stripper member is disposed parallel to the fuser member. The endless rotary belt is looped for rotation around the fuser member and the stripper member in a longitudinal, conveyance direction of the belt. The heater is disposed adjacent to the belt to heat the belt. The pressure member is disposed opposite the fuser member via the belt. The fuser member and the pressure member press against each other via the belt to form a fixing nip therebetween. The recording medium after passage through the nip remains in contact with the belt as the belt moves from the fuser member toward the stripper member, and separates from the belt as the belt passes around the stripper member.

摘要： A glossing device includes a heater member, a stripper member, an endless rotary belt, a pressure member, and a belt cooler. The heater member is subjected to heating. The stripper member is disposed parallel to the heater member. The endless rotary belt is looped for rotation around the heater member and the stripper member in a longitudinal, conveyance direction of the belt. The pressure member is disposed opposite the heater member via the belt. The heater member and the pressure member press against each other via the belt to form a glossing nip therebetween. The recording medium after passage through the nip remains in contact with the belt as the belt moves from the heater member toward the stripper member, and separates from the belt as the belt passes around the stripper member. The belt cooler is disposed adjacent to the belt to cool the belt.
