Abstract: A fixing unit includes a plurality of first engagement portions which respectively engage with a plurality of first to-be-engaged portions to restrict a movement of a heating unit in a third direction intersecting with a first direction and a second direction. A fixed unit includes a second engagement portion which engages with a second to-be-engaged portion to restrict a movement of the heating unit in the first direction. The fixing unit includes a movable unit, a supporting member, and a reciprocating mechanism. The supporting member supports the movable unit such that the movable unit is movable along the first direction. The reciprocating mechanism causes the movable unit to reciprocate. The reciprocating mechanism causes the movable unit to reciprocate once every time a plurality of sheets pass between a first rotation member and a second rotation member in the fixing unit.

Abstract: A heating unit includes a to-be-engaged portion. A fixing unit includes an engagement portion. The heating unit or the fixing unit includes an engagement guide portion. A movement mechanism retains the heating unit in a tilted attitude when causing the heating unit to move at a position set apart from the fixing unit. The engagement guide portion causes the heating unit to rock from the tilted attitude to a reference attitude while guiding the to-be-engaged portion to the engagement portion. The engagement portion engages with the to-be-engaged portion to restrict a movement of the heating unit in a longitudinal direction. A unit bias portion retains an engagement state between the engagement portion and the to-be-engaged portion.

Abstract: In an image formation device, a driven gear is coupled to a far end portion in a unit inserting and withdrawing direction of a rotary fixing member or a rotary pressure member of a fixing unit. A driving gear is provided in a far end portion of a fixing unit housing part and engages with the driven gear when the fixing unit is housed in the fixing unit housing part. The driving gear and the driven gear are formed so that a transmission force transmitted from the driving gear to the driven gear in a mutual engagement position has a component so directed as to horizontally press the fixing unit against columns making a pair. The fixing unit as housed in the fixing unit housing part is pressed by the transmission force against the columns and positioned in a direction orthogonal to the unit inserting and withdrawing direction.

Abstract: A heating unit urging member urges a first support body of a heating unit toward a second support body of a fixing unit with elastic force. The heating unit urging member brings the first support body into contact with the second support body and brings the second support body into contact with two struts. An interlocking mechanism moves the heating unit along a direction in which the heating unit and the fixing unit are arranged, in conjunction with movement of an operation portion. When the operation portion moves from a first position to a second position, the interlocking mechanism moves the first support body from a reference position where the first support body is in contact with the second support body to a retracted position where the first support body is separated from the second support body.
