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.
