ABSTRACT:
A method for adjusting toner density is provided for an image recording apparatus which stores a weighted value table having weighted values corresponding to toner consumption coefficients and a driving table having driving times of a toner supply motor corresponding to the weighted values. The method is carried out by calculating a toner consumption coefficient for each line of a page. This is performed by dividing a number of black data bits represented on each line by a total number of data bits represented on each line. Weighted values corresponding to the calculated toner consumption coefficients are then obtained from the weighted value table. From these weighted values, an average weighted value for the page is generated. The driving table is then searched to locate a driving time corresponding to the average weighted value. The toner supply motor is driven in accordance with the driving time to thereby adjust the toner density while printing the page.
