ABSTRACT:
A roller supporting arrangement for an electrostatic copying apparatus having a plurality of pairs of copy paper transport rollers spaced along a copy paper transport passage includes a support frame for supporting the lower rollers of the respective pairs of transport rollers. A support shaft is mounted horizontally to a copying apparatus housing, by which the support frame is rotatably supported. A device is provided for pushing up the support frame and for releasing the support frame from the push-up force to be turned downward about the support shaft. Since the lower rollers of the pairs of the rollers mounted at the copy paper sheet transport passage are connected pivotally to the support frame which is rotatable about the horizontal support shaft, it is easy to open the copy paper sheet transport passage when a copy paper is jammed in the copy paper sheet transport passage.
