Abstract
This invention provides an information recording apparatus, which can save the consumption amount of a toner without thinning out an image in units of pixels, and can realize smoothing processing with high image quality. In input data, a pixel corresponding to an edge portion is subjected to smoothing processing. Data of a black pixel which is not subjected to smoothing processing is recorded while saving toner by controlling the print pulse width or the print pulse number upon recording of the black pixel on the basis of a print density command.
