Abstract
A multi-beam image recording device is capable of recording high-quality high-resolution images without positional errors by exposing test patterns for measuring positional errors of beam spots of each laser beam in main and subsidiary scanning directions, calculating the positional errors of beam spots using a correcting device, controlling the quantity of exposure according to the result of calculation, and thus correcting the positional errors in main and subsidiary scanning directions.
