Abstract: A conveying belt is disposed so as to guide a recording medium on a side opposite to an image carrying belt across an extension line of a stretch surface formed by a transfer nip and a pressure member. Thus, the recording medium delivered from the transfer nip is guided on the side opposite to the image carrying belt across the extension line of the stretch surface. Therefore, even in a case of guiding a recording medium whose bending rigidity is high in particular, it is possible to suppress a rear end of the recording medium to move in a direction of separating from the image carrying belt at upstream of the transfer nip.

Abstract: In an image forming apparatus that separates a thin recording material by pushing up a transfer belt, if a position where a thick recording material separates from the transfer belt is far from a leading end of a recording-material guide, conveyability of the separated thick recording material after separation becomes stable. A stretching member is provided downstream of a push-up means and upstream of the recording-material guide in a recording-material conveying direction, and the stretching member separates a thick recording material from the transfer belt.

Abstract: An image forming device is disclosed that is able to enlarge a gap of a nipping portion with a simple and inexpensive structure, and able to reduce impact when a front end of a recording sheet runs into or a back end of the recording sheet passes through the nipping portion. The image forming device includes an image carrying unit, an image forming unit, a transfer unit, a conveyance unit, a determination unit that determines whether a thickness of the recording sheet is greater than a threshold value, and a cam member that rotates to enlarge or reduce the gap of the nipping portion between the image carrying unit and the transfer unit according to rotational positions of the cam member. When the thickness of the recording sheet is greater than the threshold, the cam member rotates so that the gap of the nipping portion is enlarged.
