Abstract
A fixing device is provided with a first rotating member, a second rotating member in contact with the first rotating member, a first drive motor for rotationally driving the first rotating member, a second drive motor for rotationally driving the second rotating member, a torque limiter provided between the second rotating member and the second drive motor, and a pressure adjusting mechanism for adjusting the nip pressure between the first rotating member and the second rotating member. When the nip pressure is greater than the maximum torque that can be transmitted by driving the torque limiter, the second rotating member rotates following the first rotating member and at the same linear speed as that of the first rotating member, and when the nip pressure is equal to or less than the maximum torque, the second rotating member rotates at a linear speed different from that of the first rotating member.
