Abstract

A technique in an image forming apparatus in which the front and back sides of a sheet are reversed by using a reversal conveyance path is provided for causing the sheet to wait such that the sheet is not damaged when a unit for conveying the sheet to the reversal conveyance path is pulled out for the purpose of clearing a jam or the like. A roller for conveying the sheet is controlled such that the sheet to be turned back and directed into the reversal conveyance path is caused to wait until the sheet can be conveyed into the reversal conveyance path. As a standby position of the sheet while the sheet is caused to wait, a position is set such that an upstream end portion in the second conveying direction of the sheet to be directed into the reversal conveyance path does not extend for a predetermined length or longer into another conveyance unit adjacent to the intermediate conveyance unit upstream from the intermediate conveyance unit in the second conveying direction.
