Abstract
An image forming system which reduces the number of sheets invalidated upon detection of an image defect, without an escape area. The image forming system includes an image forming section, an image reading section, a post-processing section, and a controller. When the controller detects an image defect on a sheet, if the number of sheets from the spoilage sheet to the sheet in the first bunch of sheets on the border of the bunch is smaller than the number of sheets from the spoilage sheet to the last sheet, the controller continues the process to make sheet bunches up to the sheet bunch including the last sheet. Then, the controller starts recovery operation for copies (bunches) remaining to be made as requested by job information plus a copy equivalent to the sheet bunch including the spoilage sheet.
