Abstract: A fixing device includes a fixing member, a pressure roller, a discharge rollers pair, a discharge guide, and an actuator. The fixing member is heated by a heat source. The pressure roller forms a pressurized region. The discharge rollers pair includes an upper roller and a lower roller, and conveys the sheet passed through the pressurized region. The discharge guide guides the sheet passed through the pressurized region to the discharge rollers pair. The actuator includes a rotating shaft supported by the discharge guide rotatably and movably in an axial direction and a detection piece extending radially from the rotating shaft, and rotated by the sheet passed through the pressurized region to detect the sheet. The discharge guide has a slit in which the detection piece is housed to regulate a moving of the detection piece in a width direction of the sheet.

The fixing frame includes a pair of side plates and a plurality of stays. The side plates are disposed to face each other, and supports both axial end portions of the heating rotating body and both axial end portions of the pressure rotating body. The stays are disposed between the side plates. In a XYZ coordinate in which an axis along a direction in which the side plates face each other is defined as the X-axis, and axes perpendicular to the X-axis and perpendicular to each other are defined as the Y-axis and the Z-axis, each of the stays is fastened to the side plates at least two axial directions of the three axial directions of the XYZ coordinates.

Abstract: A heat roller includes a main body and a follower gear. The main body includes a cutaway portion and a pair of protruding plate portions. The follower gear includes a transmission protrusion and an abutment portion. The transmission protrusion is abutted against one protruding plate portion, when the follower gear rotates. The abutment portion is abutted against the one protruding plate portion, when the main body rotates in advance. A size of the transmission protrusion along the width direction of the cutaway portion is smaller than a clearance between the pair of protruding plate portions in the width direction, and a clearance between the abutment portion and the one protruding plate portion in the roller rotation direction is narrower than a clearance between the transmission protrusion and the other protruding plate portion in the roller rotation direction, when the transmission protrusion is in contact with the one protruding plate portion.

Abstract: An image forming apparatus includes a fixing unit and an apparatus main body. The fixing unit fixes a toner image on a recording medium. To the apparatus main body, the fixing unit is attached. The apparatus main body includes a holding part which has an opening and an elastically deformable contact part. The opening is arranged at an attachment position of the fixing unit. The contact part protrudes from an edge of the opening to an attachment direction of the fixing unit and is bent so as to narrow the opening. The fixing unit includes a held part protruding at a position corresponding to the holding part, and the held part enters the opening while pressing the contact part so that the held part fits into the opening.

Abstract: A fixing device includes a heating roller and a pressuring roller, a first holding member, a supporting member and a temperature detecting part. The heating roller and pressuring roller sandwiches and heats a sheet to fix a toner image formed on the sheet onto the sheet. The first holding member has a facing part facing to a circumference face of the heating roller to hold the heating roller. The supporting member is made of material with high heat resisting property as compared with the first holding member, arranged between the facing part of the first holding member and the circumference face of the heating roller so as to face to the circumference face of the heating roller, and formed in an elongated shape along an axial direction of the heating roller. The temperature detecting part is arranged in the supporting member to detect temperature of the heating roller.

Abstract: An image forming apparatus includes a toner case and an attachment part. The toner case includes a case main body, a rotator, a transmitter and a moving mechanism. The rotator rotates around a rotation axis. At least apart of the rotator is stored in the case main body. The transmitter is arranged outside the case main body and has a transmitting coupling. The attachment part includes a manipulation member and a driving coupling. As the manipulation member moves from a first manipulating position to a second manipulating position in a state where the toner case is attached to the attachment part, the moving mechanism moves the transmitter from a first position to a second position which is arranged at an outside of the first position in a rotation axis direction of the rotator, and the transmitting coupling is coupled to the driving coupling.
