Thereby, it is possible to effectively utilize the lateral space 8, open the conveyance path cover 82, and perform jam processing in which the sheet is taken out from the conveyance path 70.

The width dimension W100B occupied by the image forming module 100 when the transport path cover 82 is located at the open position 82B is the same as the width W100B occupied by the image forming module 100 when the transport path cover 82 is located at the cover position 82A. It is larger than the dimension W100A.

When the transport path cover 82 is located at the open position 82B, the end 820 of the transport path cover 82 on the right end (other end) 200R side of the top plate 200 in the width direction (X-axis direction) is It is located inside the right end (other end) 200R of the plate 200. That is, the widthwise dimension W100B occupied by the image forming module 100 when the conveyance path cover 82 is located at the cover position 82A is smaller than the widthwise dimension W200 of the top plate 200.

As a result, even if an object is placed on the right side of the image forming apparatus 1, jam processing can be performed in the horizontal space 8 by opening the transport path cover 82 and taking out the sheet from the transport path 70.
