Abstract: To assemble a positioning member, which is to come into abutment with a liquid ejection apparatus, to a liquid ejection member, the present disclosure has adjustment parts for adjusting positions of the positioning member and the liquid ejection member and securing parts for coupling and securing the positioning member and the liquid ejection member and thereby couples and secures the positioning member and the liquid ejection member. Thus, the positions of ejection ports of the liquid ejection head set in the liquid ejection apparatus and reference positions can be positioned with high accuracy.

Abstract: A fixing device includes a belt having a tubular shape and extending in a longitudinal direction, and having a longitudinal end, a drive roller to rotate the belt to convey a print medium between the drive roller and the belt, a bushing located at the longitudinal end of the belt, and a guide wall adjacent to the bushing. The belt is displaceable in the longitudinal direction relative to the bushing. The bushing includes a shoulder adjacent to the longitudinal end of the belt and a stem extending from the shoulder to an inside of the belt to support the belt. The guide guides the bushing to move in a direction opposite to a conveyance direction of the print medium when the belt moves toward the bushing. The stem of the bushing includes a convex portion that is in contact with an inner surface of the belt when the belt is displaced in the longitudinal direction.

Abstract: A fixing apparatus can include a heater roller, a tension roller, a belt movable from the heater roller to the tension roller, a pressure roller to make pressure contact with the heater roller via the belt to form a fixing nip, and a blower member including a first opening to direct air toward the belt and a second opening to direct air toward the heater roller.

Abstract: An imaging system includes a toner image forming device and a gloss treatment device. The toner image forming device accommodates a color toner that forms a color toner image on a printing medium, and which accommodates a clear toner that forms a clear toner image on the printing medium. The clear toner has a wax content that is lower than a wax content of the color toner. The gloss treatment device melts the clear toner on the printing medium to apply gloss treatment to the printing medium including the color toner image and the clear toner image.
