摘要:
An image heating apparatus includes: a heater (300) including a substrate and a heat generating element (301); a supporting member (201); a high heat-conductive member (220). The recording material on which an image is formed is heated by heat from the heater. The supporting member has a bottom region, where the supporting member supports the heater, including a first region where the supporting member contacts the high heat-conductive member so as to apply pressure between the heater and the high heat-conductive member and including a second region where the supporting member is recessed from the high heat-conductive member relative to the first region. At least a part of the first region overlaps, with respect to a movement direction of the recording material, with a region where the heat generating element is provided.

An image fusing apparatus includes a heating belt including a resistance heating layer, an insulating layer formed on an inner surface of the resistance heating layer, and a release layer formed on an outer surface of the resistance heating layer; a heating supporting roller disposed (positioned) inside the heating belt and rotating with the heating belt; a pressing roller disposed (positioned) parallel to the heating supporting roller and in contact with the outer surface of the heating belt to form a nip; and an electricity supplying member to supply electricity to the resistance heating layer of the heating belt. A thickness of paper non-contact areas of opposite side end portions of the resistance heating layer of the heating belt is the same as or thicker than the thickness of a paper contact area of a middle portion of the resistance heating layer thereof.

An image heating apparatus (A) includes an endless belt (1) for heating an image (T) on a recording material (P); a plurality of supporting members (2,3) on which the belt (1) is trained; magnetic flux generating means (7), disposed outside of the belt (1), for generating heat in the belt (1) by a magnetic flux, the magnetic flux generating means (7) being effective to cause induction heating both in a region of the belt (1) between the supporting members (2,3) and in at least one of the regions of the belt (1) trained on the supporting members (2,3); a temperature detecting element (TH1;TH2) for detecting a temperature of the belt (1) in the region between the supporting members (2,3) at a position across the belt (1) from the magnetic flux generating means (7); and electric power supply shut-off means (100) for shutting off electric power supply to the magnetic flux generating means (7) on the basis of an output of the temperature detecting element (TH1,TH2).
摘要:
Systems and methods of inductively heating a fuser member in an electrophotographic device are disclosed. The systems and methods can include a heating component with a susceptor layer comprising carbon nanotubes (CNTs). An excitation unit with an electrical coil can be positioned a proximate distance from the heating component. Current through the electrical coil can inductively heat the susceptor layer and the heating component. The heat from the susceptor layer and the heating component can be used to fuse toner onto an image-receiving substrate. The CNTs can reduce electronic hardware costs in the electrophotographic device in relation to the costs associated with conventional materials.
