The image forming unit includes an image carrying member. The sheet discharge unit is disposed above the image forming unit. The sheet discharge port is provided in the sheet discharge unit and has an upper edge and a lower edge. The pair of sheet pressing members press the sheet passing through the sheet discharge port. The overhang portion protrudes from the upper edge of the sheet discharge port in the sheet discharge direction beyond the lower edge. The overhang portion is disposed such that the straight line passing through the distal end of the overhang portion and the lower edge of the sheet discharge port passes above the image carrying member.

Abstract: A fixing device includes a fixing member, a heat source, a pressing member and a holding member. The holding member includes a base plate and a sliding sheet. The base plate includes a main body and a projection. The main body has one face facing an inner circumferential face of the fixing member and the other face opposite to the one face. The projection is formed on the other face. The sliding sheet has a through hole into which the projection is fitted. The sliding sheet is wrapped around the main body with the projection fitted into the through hole. The sliding sheet is subjected to a heat treatment at a temperature higher than a maximum temperature where a temperature of the fixing member reaches when the fixing member is heated by the heat source.

Abstract: A fixing device includes a fixing belt, a pressuring member, a heat source and a reflecting member. The fixing belt is arranged rotatably around a rotation axis. The reflecting member reflects the radiant heat radiated from the heat source. The fixing belt has a passing region and a non-passing region. Through the passing region, a recording medium passes. The non-passing region is arranged outside the passing region in a direction of the rotation axis. The reflecting member has a first reflecting part and a second reflecting part. The first reflecting part is arranged at an inner circumferential side of the passing region. The second reflecting part is arranged at an inner circumferential side of the non-passing region. Roughness of a face at the heat source side of the second reflecting part is larger than roughness of a face at the heat source side of the first reflecting part.

Abstract: A fixing device includes a fixing belt, a pressuring member, a pressing member, a heat source and a heat transmitting member. The fixing belt is arranged rotatably. The pressuring member is arranged rotatably to come into pressure contact with the fixing belt so as to form a fixing nip. The pressing member presses the fixing belt to a side of the pressuring member. The heat source is arranged at the inside in a radial direction of the fixing belt to radiate a radiant heat. The heat transmitting member comes into contact with an inner circumference face of the fixing belt to absorb the radiant heat radiated from the heat source. A part of the heat transmitting member is sandwiched between the fixing belt and the pressing member.

Abstract: The fixing device includes a heating roller and a pressure roller. The heating roller has a rotating member, a heating member, and a support member. The heating member has a heater, a first terminal, and a second terminal. The heater generates heat by energization. The first terminal is connected to one end of the heater. The second terminal is connected to the other end of the heater. The first terminal protrudes from one end of the rotating member in the longitudinal direction of the rotating member and is hooked on a hook provided on the support member so as to be movable along the longitudinal direction. The second terminal protrudes from the other end of the rotating member in the longitudinal direction and is fixed to the support member so as not to be movable along the longitudinal direction.
