摘要： PROBLEM TO BE SOLVED: To obtain an image formation device that can improve position accuracy of a rear end regulation member to a transfer body in a circumferential direction of the transfer body.SOLUTION: Rotary force is transmitted from a driving motor M1 to a rear end gripper 34 and a transfer drum 30 via a rotary force transmission unit 52, and the transfer drum 30 and the rear end gripper 34 are synchronously rotated. In this way, since the driving motor M1 transmits the rotary force for rotating the transfer drum 30 to the rear end gripper 34 using the rotary force transmission unit 52, in comparison with a case where a transmission unit is individually provided, the position accuracy of the rear end gripper 34 to the transfer drum 30 in the circumferential direction of the transfer drum 30 is improved.
摘要翻译：要解决的问题：获得能够提高后端调节构件在转印体的周向上的转印体的位置精度的图像形成装置。解决方案：旋转力从驱动电动机M1传递到后端夹持器34和转印鼓30经由旋转力传递单元52和转印鼓30和后端夹持器34同步旋转。以这种方式，由于驱动电机M1使用旋转力传递单元52将用于使转印鼓30旋转到后端夹持器34的旋转力与单独设置传动单元的情况相比较，所以位置精度在转印鼓30的圆周方向上的转印鼓30的后端夹持器34得到改善。

摘要： PROBLEM TO BE SOLVED: To inhibit failure of gripping a recording medium when and after the tip of the recording medium is gripped.SOLUTION: A transfer drum 30 includes a cylinder part 31, a tip gripper 32, and a contact part 100 for pinching recording paper P together with the tip gripper 32. The contact part 100 is provided with a first friction part 102 having a first friction coefficient μ1 and a second friction part 104 having a second friction coefficient μ2 higher than the first friction coefficient μ1. The first friction part 102 is placed above the second friction part 104. When the tip of the recording paper P enters between the contact part 100 and the tip gripper 32, the recording paper P is first brought into contact with the first friction part 102, so that the recording paper P can enter smoothly and can be inhibited from being caught. The entered recording paper P is gripped at least by the second friction part 104 and the tip gripper 32, so that a gripping state of the recording paper P can be maintained.
