ABSTRACT:
An image recording apparatus for electrostatically forming a latent image on an image carrier by driving optics in response to multi-level image data. Before the start of an actual image recording operation, a latent image in the form of a test pattern having a plurality of tones is formed on the image carrier by pulse width modulation. A table for correcting image data is generated on the basis of sensed surface potentials of the test pattern. A semiconductor laser included in the optics is driven such that the tone data and the latent image potential remains in a constant relation.
