Abstract

In a sheet conveying apparatus (102) having a jam detecting means, there are provided an accommodating portion (201) for jam treatment and a conveyance controlling means to accommodate sheets on a conveyance path into said portion, enabling all the sheets on the path to be gathered in one place and rendering the removal treatment easier. In another aspect of this invention, in case of jam occurrence, the sheets being conveyed are temporarily accommodated in the standby accommo­ dating portion (201) for discharge and then rejected outside the apparatus after jam return, while an image forming portion carrying out the image formation onto the sheets to be accommodated so that they can be discharged as regular output sheets, and image formation being prohibited when the sheets are discharged, resulting in that the image previously formed on the sheets is not be disturbed.
