An image forming apparatus includes an image output unit that outputs an image to a continuous paper; a generator that generates an image based on a print instruction by executing drawing processing; a determining unit that determines an image layout to output a plurality of images on the continuous paper in parallel based on at least two print instructions; and a combining unit that combines the plurality of images generated by the generator on the basis of the image layout determined by the determining unit; a controller that controls the image output unit so that the plurality of images combined by the combining unit is output to the continuous paper.
