Abstract
A multi-beam image recording apparatus changes a diameter of a laser beam using a beam diameter changing board, an order in which the line data is to be read from the memory unit, a rotational speed of a polygon mirror, and a clock frequency employed when the image data is read in units of pixels, in accordance with the specified resolution. Accordingly, the multi-beam image recording apparatus can switch between the resolutions without changing a distance between the centers of two laser beams emitted from an optical system. The resolution switching can be achieved with high accuracy at low costs.
