摘要： To provide an image forming apparatus capable of increasing the life of a rotating cam while preventing the occurrence of a shock jitter and transfer failure. The image forming apparatus is configured to execute a forced movement process for rotating the rotating cam to forcibly move a secondary transfer roller against a biasing force of a bias coil spring at a pre-entry timing prior to the entry of the front edge of a recording sheet into a secondary transfer position, and a pressure intensifying process for rotating the rotating cam to increase transfer pressure at a timing immediately after the entry of the front edge of the recording sheet into the secondary transfer position. As the forced movement process, the image forming apparatus executes, alternately, a first forced movement process for normally driving and rotating the rotating cam, and a second forced movement process for inversely driving and rotating the rotating cam, at a predetermined timing.

摘要： A secondary transfer facing roller includes a roller part that has a through-hole penetrating in a rotary shaft line direction at a rotation center position, and a penetrating shaft member penetrating the through-hole of the roller part and spinning the roller part on a surface of the penetrating shaft member. Eccentric cams are fixed to both end regions that are not located in the roller part, so as to rotate integrally with the penetrating shaft member. A position regulating cam and an abutting roller form a gap between the intermediate transfer belt and the secondary transfer roller immediately before a transfer sheet enters a transfer nip part. While the gap is formed, current flows between the intermediate transfer belt and the secondary transfer roller via the position regulating cam and the abutting roller.

摘要： A transfer assembly includes a counter member having a contact face, an engagement/disengagement unit to engage and disengage the image carrying face of image carrying member and the contact face of counter member using a cam, a pressure device to apply force to a transfer nip between the image carrying face and contact face, and a recording medium feed device to feed the recording medium to the transfer nip. When the cam is at a first rotation position, the image carrying face and contact face are separated, and when the cam is at a second rotation position, the image carrying face and contact face contact. Before the recording medium enters the transfer nip, the cam rotates from the first rotation position toward the second rotation position. After the recording medium enters the transfer nip, the cam is at the second rotation position to press the image carrying face with the contact face.
摘要翻译：传送组件包括具有接触面的对置构件，接合/分离单元，用于使用凸轮接合和分离图像承载构件的图像承载面和相对构件的接触面;压力装置，用于向转印压区施加力在图像承载面和接触面之间，以及记录介质供给装置，用于将记录介质输送到转印辊隙。当凸轮处于第一旋转位置时，图像承载面和接触面被分离，并且当凸轮处于第二旋转位置时，图像承载面和接触面接触。在记录介质进入转印辊隙之前，凸轮从第一旋转位置转动到第二旋转位置。在记录介质进入转印辊隙之后，凸轮处于第二旋转位置，以用接触面按压图像承载面。
