Image forming apparatus with leading-end and trailing-end holding members to prevent sagging of recording medium during transportation
Abstract:
An image forming apparatus includes an image carrying member, a transfer member, a leading-end holding member, and a trailing-end holding member. The leading-end holding member is mounted on the transfer member and holds, on an outer peripheral surface of the transfer member, a leading-end portion of a recording medium fed to a sheet feeding position that is further upstream than a transfer position in a rotation direction of the transfer member. The trailing-end holding member rotates along the outer peripheral surface. The trailing-end holding member presses the recording medium against the outer peripheral surface while waiting at a waiting position that is further upstream than the transfer position and downstream than the sheet feeding position, and holds a trailing end portion on the outer peripheral surface while rotating together with the transfer member when the trailing end portion of the recording medium arrives at the waiting position.
