摘要： PROBLEM TO BE SOLVED: To provide an image forming device capable of suppressing image defect generated by transmitting vibration generated when a tip holding member for holding the tip of a recording medium holds the recording medium to an exposure position of an image holding body.SOLUTION: Exposure is started after holding the tip of a first (the preceding) sheet member P1 by having a predetermined lay-out, and the exposure is completed before holding the tip of a second (the following) sheet member P2. That is, in a state where the exposure is performed, holding action for holding the tip of the sheet member P is not performed. Due to this reason, image defect can be suppressed which is generated by transmitting vibration generated by holding action for holding the tip of the sheet member P to an exposure position Ro of an image holding body 22.
摘要翻译：要解决的问题：提供一种图像形成装置，其能够抑制当用于保持记录介质的末端的末端保持构件将记录介质保持在图像保持体的曝光位置时产生的振动而产生的图像缺陷。解决方案：通过具有预定的布置来保持第一（前一个）片材P1的尖端之后开始曝光，并且在保持第二（下一个）片材P2的尖端之前完成曝光。也就是说，在进行曝光的状态下，不进行保持片材P的前端的保持动作。由于这个原因，可以抑制图像缺陷，这是通过将通过保持片材P的尖端的保持动作产生的振动发送到图像保持体22的曝光位置Ro而产生的。

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing a leading edge side of a recording medium wound around a transfer body from floating from the transfer body.SOLUTION: A peripheral speed V1 of an image holding body 22 is faster than a peripheral speed V2 of a transfer drum 30; and therefore, a conveying speed of a sheet member P at a transfer position Tr increases in accordance with the peripheral speed of the image holding body. Consequently, a leading edge side of the sheet member P may float from an elastic layer 30C. However, the leading edge side of the sheet member P is pressed against a support surface 60 by a regulating member 50, floating of the leading edge side of the sheet member P is suppressed (attitude is stabilized).
摘要翻译：要解决的问题：提供一种能够抑制卷绕在转印体上的记录介质的前缘侧从成像体浮起的图像形成装置。解决方案：图像保持体22的圆周速度V1比转印鼓30的圆周速度V2; 因此，转印位置Tr处的纸张P的输送速度根据图像保持体的圆周速度而增加。因此，片材P的前缘侧可以从弹性层30C浮起。然而，片状构件P的前缘侧通过限制构件50压靠在支撑面60上，片材P的前缘侧的浮动受到抑制（姿势稳定）。
