Abstract
This invention solves problems such as density shortage, toner scattering, and toner fog when images whose density is biased are successively printed. In order to achieve this purpose, an image processing equipment comprising an input unit which inputs a print job, an image processing unit which generates print data corresponding to the input print job and supplies the print data to an image forming unit, a detector which detects bias of the amount of toner application distribution in the print data, and a control unit which controls said image processing unit so as to rotate an output direction of the print data on the basis of a detection result of said detector.
Claims24
An image processing equipment comprising:
- a receiving unit which receives a print job from an external apparatus;
- an image processing unit which generates print data corresponding to the print job and supplies the print data to an image forming unit;
- a counter which counts a video count value of the print data generated by said image processing unit in a first scanning direction or a second scanning direction;
- an acquisition unit which, when a print job which is formed from master data serving as a fixed image and variable data serving as a variable image is designated, acquires a video count value of the mater data from said counter;
- a comparator which compares the video count value acquired by said acquisition unit with a predetermined threshold;
- and
- a control unit which, when the video count value exceeds the threshold as a result of the comparison, controls said image processing unit so as to rotate an output direction of the print data every predetermined number of print sheets.
