ABSTRACT:
A toner consumption measuring apparatus having an effective signal generating unit to receive inputs of printing data and a video clock signal to synchronize the printing data and to generate a count effective signal, a counting unit to count the generated count effective signal and to calculate a number of pixels of the printing data, a coefficient memory to store at least a toner consumption coefficient of a unit of pixel ‘K’ which is set in advance, and a printer control unit to determine an image pattern compensation coefficient by using the differences of numbers of the pixels of adjacent lines of a page in printing of every page, and calculating a toner consumption with applying a proper weight in accordance with the determined image pattern compensation coefficient.
