Abstract
An image forming apparatus with toner saving mode is disclosed. This image forming apparatus comprising a normal ditheringing matrix and a toner saving mode ditheringing matrix having threshold data higher than that of the normal ditheringing matrix. The normal ditehring matrix is for image data processing under non-toner saving mode and the toner saving mode matrix is for image data processing under toner saving mode. The selection of the dithering matrix is executed by a central processing unit in response with the existance of order for toner saving. The processed image data processed by one of the dithreing matrix maintains the expression of linear tonality.
