Abstract
An image forming apparatus capable of detecting a precise toner consumption amount has a system counting up a turned-on dot number of image data, outputting weight factors corresponding to the respective sub-line's numbers based on the respective sub-line numbers of the plural sub-lines at which a light emitting amount of each dot is varied periodically, and calculating the light emitting amount based on a dot counter value of the turned-on dot number and the weight factor corresponding to the respective sub-line's numbers, to summate the calculated light emitting amounts to estimate the toner consumption amount with high accuracy.
