Image forming apparatus for enlarged divisional printing

An image forming apparatus capable of enlarged divisional printing wherein an image is formed by enlarging and dividing image data into image data of a plurality of pages, and full breed print wherein the image is formed to a very edge of a sheet, the image forming apparatus, comprising:

• an input section for setting the enlarged divisional printing;
• a control section for automatically setting the full breed print in case the enlarged divisional printing is set through the input section;
• an image carrier for carrying a toner image;
• a sheet feeding section for feeding the sheet on which the toner image is transferred;
• a transfer roller for transferring the toner image on the image carrier onto the sheet;
• and
• a cleaning section for cleaning the transfer roller,
• wherein the control section controls the cleaning section to execute cleaning of the transfer roller after the transfer roller transfers the toner image onto the sheet and before the transfer roller transfers the toner image onto a succeeding sheet in a way that a cleaning time in full breed printing, where enlarged divisional printing is set, is shorter than the cleaning time in full breed printing, where enlarged divisional printing is not set.
