ABSTRACT:
An image forming apparatus includes a photosensitive drum which is exposed by a line head. The line head includes a fluorescent head having a plurality of individually driveable light points which are aligned in a plurality of sublines in the direction of the width of the photosensitive drum. Respective light points of the fluorescent head are driven by a line driver in accordance with drive data from a shift register which holds the drive data for all the light points. One print line is formed by a set of four sublines. In the case where the thinning of a line width is to be corrected, the print line is formed by sublines generated according to a fattening amount, whereby the line width is fattened. When the apparatus is used as a facsimile or a printer, a fattening amount for a facsimile or a fattening amount for printer is set.
