Abstract:
A pressurizing unit includes a contact-pressure member for pressurizing an endless belt, a holding member that holds the contact-pressure member, and a biasing member that presses both ends of the holding member. The biasing member presses the holding member, so that a direction in which the biasing member presses the holding member is substantially the same as a direction in which the holding member presses the pressure-contact member.
