    摘要: An image forming apparatus has a main body (10) to which is attached a device (12) for cutting paper from a roll and discharging the cut paper through an outlet. The cutting device is selectively shiftable to a feed position where the outlet (110) is in register with a sheet inlet (28) on the main body or to a standby position away from the feed position. The invention also provides a roll paper cutting device for transporting and cutting roll paper having detecting means (270) disposed in the path of transport of documents for detecting a document rear end so as to cut the paper with timing based on the time when the rear end is detected. There is also provided a roll paper cutting device adapted to drive transport rollers with predetermined timing based on the time when the paper travel is detected while all the transport rollers rotate idly in a standby state for paper feeding. Finally, a roll paper cutting device is provided for feeding roll paper to the main body of an image forming apparatus by forwarding the leading end of the paper to feed means (22) disposed in said main body in the paper path to the image forming station, and thereafter transporting the paper onwards by the transport means within the main body.
