To prevent an unnatural white area from occurring on the periphery of a drawing object for which raster image generation processing on the premise that the background is white has been performed in a situation in which layer printing is performed. An information processing apparatus specifies a cutting off-target area in an image object included in input drawing data, changes the input drawing data so that the specified cutting off-target area in the image object is not drawn, and generates a print job based on the changed drawing data.

An image forming apparatus includes a rotational photosensitive member, an exposure device including a plurality of light emitting elements and a driving unit, an output unit configured to superimpose a clock signal on image data, and output the image data as serial data, a generation unit configured to recover and generate the clock signal superimposed on the image data, a conversion unit configured to receive the serial data and convert the received serial data into parallel data, a lock signal output unit configured to lock the generation unit and output a lock signal in a case where the generation unit generates the clock signal at a predetermined frequency, and a control unit configured to count a number of times the conversion unit has not received the serial data normally during a predetermined period, and unlock the generation unit in a case where the number of times exceeds a predetermined value.
