Abstract: A fixing device includes a fixing belt, a pressuring member, an exciting coil and a belt guide. The pressuring member comes into pressure contact with the fixing belt to form a fixing nip. The exciting coil is provided at an outer diameter side of the fixing belt and configured to generate a magnetic flux to inductively heat the fixing belt. The belt guide supports the fixing belt from an inner diameter side. The belt guide includes a contact part which is in contact with an inner circumferential face of the fixing belt and a non-contact part which is not in contact with the inner circumferential face of the fixing belt. A magnetic flux blocking member configured to block the magnetic flux that passes through the fixing belt is provided between the fixing belt and the non-contact part.

Abstract: An image forming apparatus includes an image forming portion, a fixing device, an input portion, and a control portion. The fixing device includes a rotary member to be heated, a pressure-applying rotary member, a heat-applying portion, a pressure-applying mechanism, and a reference position detection mechanism. The control portion controls fixing processing, with the pressure-applying rotary member disposed at any of a plurality of pressure-applying positions and a pressure reduction position based on a type of the recording medium inputted through the input portion. The control portion performs control so that when a prescribed amount of time has elapsed or when a rotation amount of a shaft has reached a prescribed amount from timing at which a reference position detection sensor is brought to an on-state, the pressure-applying drive motor is stopped so as to dispose the pressure-applying rotary member at any of the plurality of pressure-applying positions.

Abstract: The fixing device (13) includes the fixing belt (20), the pressuring roller (21) and the pad (24). The pad (24) sandwiches the belt (20) with the roller (21) to form the fixing nip. The pad (24) is extended in the nip width direction, and the pressing face (40) has the first and second curved faces (41) and (42) at upstream and downstream sides in the sheet conveyance direction. The first and second curved faces (41) and (42) are formed arch-like curved to the roller (21) toward upstream and downstream sides. The first and second curved faces (41) and (42) continue at the inflection point (B) near the intersection point of the extending line (A) parallel to the pressuring direction and through the rotation center of the roller (21) on the pressing face (40). The first curved face (41) has the curvature radius (Ra) larger than the second curved face (42).

Abstract: A fixing device includes an endless fixing belt, a belt guide, and a frame member. The belt guide has a fastening portion, an arc portion, and a contact portion. The fastening portion is fastened to the frame member. The arc portion extends from the fastening portion while curving in an arc shape along the inner circumferential face of the fixing belt and has an elastic force acting outward in the radial direction. The contact portion extends from one end of the arc portion in the circumferential direction toward the frame member and has a counter-face facing the inner circumferential face of the arc portion. The frame member has a regulating portion that extends toward the belt guide to make surface contact with, so as to overlap, the counter-face of the contact portion.

Abstract: A fixing device includes a fixing belt, a belt guide, a pressuring member, a heat source and an excessive temperature rise preventing device. The guide contacts with the inside of the belt to assist the belt's rotation track. The heat source is located across the belt to the pressuring member to induction-heat the belt. The preventing device has first and second lead wires connected at one and another end sides in an axial direction of the belt and prevents excessive temperature rise of the guide in noncontact. The first lead wire is extended to one end side and pulled out from the inside to the outside via one end side in the belt. The second lead wire is extended to another end side, curved toward one end side, extended to one end side and pulled out from the inside to the outside via one end side in the belt.
