Image forming apparatus, image forming system, image forming method, and image forming apparatus-specific program

An image forming system comprising:

• an image forming apparatus;
• and
• a post-processing apparatus connected to the image forming apparatus via a carriage path for carrying continuous paper, wherein
• the image forming apparatus includes
• a hardware processor that accepts a stop position of the continuous paper on the carriage path,
• a carrier that carries the continuous paper along the carriage path,
• an image former that forms an image on the continuous paper to be carried,
• a fuser that heats and presses the continuous paper passing through a nip portion formed by pressing bodies of revolution against each other to fix the image formed on the continuous paper, and
• the hardware processor that switches between first control that, after the last image formed most upstream in a travel direction of the continuous paper among the images formed on the continuous paper passes the fuser, stops carriage of the continuous paper and then separates the pressed bodies of revolution, and second control that separates the pressed bodies of revolution and then stops the carriage of the continuous paper, on the basis of the accepted stop position, and
• the post-processing apparatus performs post-processing on the continuous paper carried from the image forming apparatus via the carriage path.

An image forming method by an image forming apparatus that is connectable to a post-processing apparatus via a carriage path for carrying continuous paper, the image forming method comprising:

• (a) accepting a stop position of the continuous paper on the carriage path;
• (b) carrying the continuous paper along the carriage path;
• (c) forming an image on the continuous paper to be carried;
• (d) heating and pressing the continuous paper passing through a nip portion formed by pressing bodies of revolution against each other to fix the image formed on the continuous paper;
• and
• (e) switching between first control that, after the last image formed most upstream in a travel direction of the continuous paper among the images formed on the continuous paper passes a fuser, stops carriage of the continuous paper and then separates the pressed bodies of revolution, and second control that separates the pressed bodies of revolution and then stops the carriage of the continuous paper, on the basis of the accepted stop position.
