A fusing device with improved fusing performance to obtain superior gloss and gloss uniformity. The fusing device includes at least one heat source to generate heat, a fusing belt disposed near the heat source, a rotation unit contacting an outer circumference of the fusing belt, at least one pressurization unit pressed toward the rotation unit such that a fusing nip is formed between the fusing belt and the rotation unit, a heat conductor contacting an inner surface of the fusing belt to conduct heat to the fusing nip, and an intermediate unit disposed between the pressurization unit and the heat conductor to prevent transmission of heat from the heat conductor to the pressurization unit.

Fusing device and image forming device comprising the same

An image forming element includes an image drum including a plurality of ring electrodes and a slot. The plurality of ring electrodes are formed to be spaced apart from one another on a circumference of the image drum. The slot is formed in a longitudinal direction on the image drum. A connecting member includes a plurality of connecting electrodes and is disposed inside the image drum so that an end of the connecting member is received in the slot. The connecting electrodes are electrically connected with the ring electrodes one to one on the same line.

Image forming element and manufacturing method thereof

Disclosed are a fusing device with improved temperature increase and fusing performance characteristics and an image forming apparatus having the same. The fusing device can include a heater to generate heat, a fusing belt arranged around the heater, a rotating member, a press member and a heat shield unit. The rotating member may be configured to come into contact with an outer periphery of the fusing belt. The press member may be configured to be press a portion of the fusing belt toward the rotating member to define a fusing nip between the fusing belt and the rotating member. The heat shield unit configured to surround the press member to reduce the amount of heat delivered to the press member.

Fusing device and image forming apparatus having the same

An image heating apparatus including: a pressure member; a fixing roller to rotate on the pressure member; a heater to heat an external surface of the fixing roller; and a film to be heated by the heater. While passing through a gap between the pressure member and the fixing roller, the film may form a nip with the pressure member. The image heating apparatus may reduce an initial warm-up time through a film heating operation, and may utilize the fixing roller as a heat reservoir by heating the fixing roller.

Apparatus and method of heating image on recordable material

An image heating apparatus includes a pressure roller, a belting film to circulate while partially connecting with the pressure roller, a support member to be provided in the belting film and comprises a guide to guide the circulating of the belting film, a nip spring to comprise a nip portion to form a nip between the belting film and the pressure roller, and a support portion to support the nip portion against the support member, and a heater to be provided adjacent to the nip spring and transfer heat to the image through the belting film.
