摘要:
An image forming system which is capable of preventing paper jam from occurring in a sheet processing apparatus to thereby maintain the stability of the system. An alignment plates of an alignment unit movable in a lateral direction each sheet are brought into abutment with opposite side edges of sheets stacked on the sheet stack unit to laterally align the sheets. A lateral registration sensor unit detects a lateral position of the sheet being conveyed. When the detected lateral position of the sheet is beyond a predetermined position, the CPU of the apparatus changes the standby positions of the alignment plates such that spacing therebetween in the lateral direction the sheet is widened by a predetermined amount, and extends the conveying interval of sheets in the image forming apparatus by a predetermined time period.
