Abstract
Image data is input through an image data input means, and stored into an image data storage means on a job basis. The volumes of the respective stored jobs are recognized by a job volume recognition means. A processing priority determination means determines an output processing priority order of the stored jobs based on the recognized job volumes. An interrupt can be generated for a priority job even during output processing of another job according to the output processing priority order.
Claims14
An image forming apparatus comprising:
- image data input means for inputting image data;
- image data storage means for storing the input image data in units of a job that requires image formation;
- job volume recognition means for recognizing volumes of the respective jobs stored in the image data storage means;
- and
- processing priority determination means for determining a processing priority order of the jobs stored in the image data storage means based on the job volumes recognized by the job volume recognition means and for prohibiting a job from being skipped that has been skipped a predetermined number of times.
