Abstract
When image data from an external device is image data for proof printing, the number of pages of image data is calculated. Further, the percentage of a character image region and the percentage of a photographic image region in all the image data are determined. A reduction in toner consumption is determined according to the number of pages, the percentage of the character image region and the percentage of the photographic image region, and a document is then printed.
Claims12
An image forming apparatus comprising:
- a receiving section which receives image data from an external device;
- a decision section which makes a decision of whether image data received by the receiving section is image data for proof printing;
- a page number calculation section which, when the decision section decides that the image data is image data for proof printing, calculates the number of pages of image data received by the receiving section;
- a determination section which determines a print-time toner saving intensity on the basis of the number of pages calculated by the page number calculation section;
- and
- a print section which prints the image data with the toner consumption saved more than usual on the basis of the toner saving intensity determined by the determination section.

An image forming apparatus comprising:
- a receiving section which receives image data from an external device;
- a calculation section which calculates the number of pages and the number of copies of image data received by the receiving section;
- a multiplication section which multiplies the number of pages and the number of copies calculated by the calculation section to provide the number of printouts;
- a determination section which determines a print-time toner saving intensity on the basis of the number of printouts provided by the multiplication section;
- and
- a print section which prints the image data with the toner consumption saved more than usual on the basis of the toner saving intensity determined by the determination section.
