ABSTRACT:
The present invention relates to a laser scanning apparatus, which includes a drivingly rotatable subscanning drum and at least one nipping roller rotatable by the drum in pressing contact therewith and having an outer peripheral surface provided by an elastic member. The drum and the roller have their axes spaced at a constant distance from each other at all times for transporting a sheet when nipped therebetween, so that the sheet, while being transported, can be scanned with a laser beam in a direction perpendicular to the direction of transport of the sheet.
