Image forming apparatus, control method and computer-readable recording medium dividing a print job into a plurality of short jobs

A control method for an image forming apparatus of a roll-to-roll type, the image forming apparatus including an image bearing member configured to bear toner, and an image former configured to perform printing, on a roll sheet, an image formed by performing light exposure and a development process on the image bearing member, the control method comprising:

• a first process of dividing a job pertaining to a printing execution command into a plurality of short jobs;
• and
• a second process of stopping conveyance of the roll sheet and forcibly ejecting degraded toner from a developing device of the image former at a pause timing between short jobs temporally adjacent to each other among the plurality of short jobs at execution of printing,
• wherein in the first process, a job content of each of the plurality of short jobs is set such that an image of a printing target is inverted upside down for each job switching of the plurality of short jobs.

A computer-readable recording medium storing a control program of an image forming apparatus of a roll-to-roll type, the image forming apparatus including an image bearing member configured to bear toner, and an image former configured to perform printing, on a roll sheet, an image formed by performing light exposure and a development process on the image bearing member, the program comprising:

• a first process of dividing a job pertaining to a printing execution command into a plurality of short jobs;
• and
• a second process of stopping conveyance of the roll sheet and forcibly ejecting degraded toner from a developing device of the image former at a pause timing between short jobs temporally adjacent to each other among the plurality of short jobs at execution of printing,
• wherein in the first process, a job content of each of the plurality of short jobs is set such that an image of a printing target is inverted upside down for each job switching of the plurality of short jobs.
