Image forming apparatus

An image forming apparatus comprising:

• an acceptance section which accepts a printing job execution instruction for executing a printing job for forming a set of partial images, respectively, on a plurality of sheets;
• a prediction section which predicts, based on margin information contained in an accepted job execution instruction accepted by the acceptance section, and indicative of a margin region as a non-image forming region defined in each of the sheets, an arrangement pattern of the plurality of sheets to be obtained as a result of execution of an accepted job as the printing job indicated by the accepted job execution instruction;
• a determination section which determines, based on the margin information, whether or not a sum of respective areas of margin regions of the plurality of sheets is greater than a threshold associated with the arrangement pattern predicted by the prediction section;
• and
• an adjusted printing section which executes an adjusted printing processing of:
• downscaling, when the determination section determines that that the sum is greater than the threshold, an overall image consisting of a set of partial images intended to be formed according to the accepted job and arranged in the predicted arrangement pattern, in such a manner as to fall within one or more sheets arranged in an altered arrangement pattern associated with the predicted arrangement pattern;
• and forming the downscaled overall image on the one or more sheets arranged in the altered arrangement pattern, wherein the number of the one or more sheets is less than that of the sheets arranged in the predicted arrangement pattern.
