Document Type and Number:
Japanese Patent JP6750478
Kind Code:
B2
Abstract:
A fixing device includes a heating body, a pressuring body, a lateral plate supporting the heating body or the pressuring body, a first supporting body supporting the heating or pressuring body, a second supporting body including a roller, a tensile spring connected between the first and second supporting bodies, an eccentric cam and a driving part. The first and the second supporting body are swingable to the lateral plate. The eccentric cam is supported between the first and second supporting bodies in the lateral plate, and is rotated while contacting with the roller to change the second supporting body, thereby changing a nip pressure of the first and second supporting bodies to a first pressure or a second pressure lower than the first pressure. In the eccentric cam, between first and second portions making the first and second pressures, at least one depression receiving insertion of the roller is formed.
