Abstract: A heating unit includes a circuit board, a plurality of heating parts, and a plurality of wiring parts. The heating parts are arranged in a first direction on a surface of the circuit board. The wiring parts are provided on the surface of the circuit board and electrically connect the heating parts and a power source to feed the heating parts. The wiring parts respectively include electrode terminal parts electrically connected to the power source outside the heating parts in the first direction. Sizes in a second direction orthogonal to the first direction of the heating parts are set to decrease gradually or stepwisely with separating in the first direction from the electrode terminal parts.

Abstract: A fixing device includes a heating section. The heating section includes a heater, a heater holding member, a heat-sensitive body, a cover member, and an urging member. The heater holding member holds the heater. The heat-sensitive body faces the heater. The cover member covers the heat-sensitive body. The urging member urges the cover member in a first direction which is toward the heater from the heat-sensitive body. The urging member extends in a second direction intersecting with the first direction and engages with the heater holding member and the cover member.

Abstract: A fixing device includes a fixing belt and a heating section. The heating section includes a heater and a heater holding member. The heater holding member has a main body portion and a plurality of ridges. The ridges include a plurality of first ridges and a plurality of second ridges. The first ridges are disposed on a central portion of the main body portion in a width direction of the fixing belt. The second ridges are disposed in an area of the main body portion at least partially extending, in the width direction of the fixing belt, from the central portion to each of opposite ends of the main body portion. The first ridges are disposed separated at a first interval. The second ridges are disposed separated at a second interval. The first interval is smaller than the second interval.

Abstract: A fixing device includes a fixing belt, a pressure member, and a heating section. The heating section faces an inner circumferential surface of the fixing belt. The heating section includes a heater and a heater holding member. The heater heats the fixing belt. The heater holding member holds the heater. The heater holding member has a first side surface, a second side surface, and an inclined slit. The first and second side surfaces are in contact with the inner circumferential surface. The first side surface has the inclined slit. The inclined slit is located in the first side surface in a direction of a rotational axis of the fixing belt. The inclined slit has one end on a side of the pressure member and the other end on an opposite side to the side of the pressure member. The other end is located nearer a middle (center) of the first side surface in the direction of the rotational axis than the one end.

Abstract: A fixing device includes a cylindrical rotatable fixing belt, a flat heater, a safety device, a heater holding part and a pressuring member. The flat heater has a plurality of heat generating parts. The safety device is arranged across two adjacent heat generating parts to interrupt power supply to the heat generating parts in a case where temperature reaches a threshold value. The heater holding part holds the flat heater so that the flat heater comes into contact with an inner circumference face of the fixing belt. The pressuring member sandwiches the fixing belt with the flat heater to form a pressuring area for sandwiching and conveying a sheet between the fixing belt and the pressuring roller.

Abstract: A fixing device includes a pressuring member, a fixing frame, a pressuring frame, a pressure changing part, a rotation detecting part and a rotation transmitting part. The pressuring member forms a fixing nip with a fixing member. The fixing frame supports the fixing member. The pressuring frame supports the pressuring member. The pressure changing part changes fixing nip pressure. The rotation transmitting part transmits rotation of the pressuring member to the rotation detecting part. The fixing frame is turnably supported around a fulcrum part provided on the pressuring frame. The pressure changing part turns the fixing frame around the fulcrum part. The rotation transmitting part has a first rotating body and a second rotating body. The first rotating body is provided on a rotation shaft of the pressuring member. The second rotating body is engaged with the first rotating body and rotatably supported around the fulcrum part.
