An image forming apparatus that converts image data into print data is provided. The apparatus includes a conversion unit configured to generate first and second print data from the image data using an error diffusion method, each piece of second print data corresponding to one of the plurality of passes; and a printing unit configured to print the second print data. The conversion unit converts the image data into the first print data using the error diffusion method, generates constraint specifying the non-print pixels in the first print data as non-print pixels in the second print data, and converts the image data into the plurality of pieces of second print data, each piece of second print data being used in one of the plurality of passes, through an error diffusion method with the constraint. The printing unit prints the second print data in each of the plurality of passes.
