PROBLEM TO BE SOLVED: To provide a drive mechanism capable of preventing a first drive part and a second drive part from being broken since excessive force is transmitted to neither the first drive part nor the second drive part even if a first rotary member and a second rotary member have peripheral speed difference, and an image formation apparatus with the drive mechanism.SOLUTION: A drive mechanism 6 has a first drive part 7, a second drive part 8, a torque limiter 73, a first rotary member 70, a one-way clutch-incorporated gear 82, and a second rotary member 80. The first rotary member 70 is connected to the first drive part 7 through the torque limiter 73, and driven to rotate when supplied with rotary drive force from the first drive part 7. The second rotary member 80 is connected to the first drive part 8 through the one-way clutch-incorporated gear 82, and driven to rotate in the opposite direction to the first rotary member 70 when supplied with rotary drive force from the second drive part 8. Further, the second rotary member 80 has a slower peripheral speed than the first rotary member 70. |
