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.
