Abstract
At the detection of an occurrence of a sheet feeder jam, in a case where media in the course of being printed on one face exist, printing this one face is continued, and this medium is inserted into the duplex printing unit.

An image forming apparatus, comprising:
- a first conveying section for conveying media,
- a first conveying section sensor for detecting the media being conveyed by said first conveying section,
- a second conveying section for reversing the media and for conveying the reversed media, and
- an image forming section for forming an image on a medium conveyed from said first conveying section or from said second conveying section,
- wherein, in case that said first conveying section conveys a second medium after conveying a first medium,
- said second conveying section conveys in said first medium from said image forming section and keeps said first medium, said first medium having completed forming an image, when a jam of said second medium is detected by said first conveying section sensor,
- said first conveying section conveys a third medium after detecting relief of the jam of said second medium with said first conveying section sensor, and
- said second conveying section conveys the kept first medium to follow said third medium.
