ABSTRACT:
In a facsimile apparatus, record density data associated with received data is used to control record density on a paper. At the same time, the emission intensity or pixel-by-pixel emission interval of a light emitting device is controlled to change tonality on a paper pixel by pixel in association with the record density. Hence, even when the record density of received data changes, the present invention prevents the density of a reproduced image from changing and prevents discontinuous lines from being undesirably exaggerated.
