Abstract:
1. An image forming apparatus that forms an image according to light emitted from a light source, the image forming apparatus comprising: circuitry including a first image processor configured to perform image processing on image data having a first resolution and output the resulting image data; a resolution converter configured to acquire the image data having the first resolution output from the first image processor and convert the image data to image data having a second resolution that is higher than the first resolution; a modulation signal generator configured to modulate the image data having the second resolution according to a clock signal to generate a modulation signal; a light source driver configured to drive the light source according to the modulation signal; and a second image processor configured to perform image processing on the image data having the second resolution to be modulated to the modulation signal, wherein the second image processor acquires object information that indicates a type of an object in the image data and determines whether or not to perform image processing based on the acquired object information, the first image processor performs image processing for at least part of a pattern of an object having a predetermined size or larger on the image data having the first resolution, and the second image processor performs image processing for at least part of a pattern of an object smaller than the predetermined size on the image data having the second resolution.
