ABSTRACT:
An image forming apparatus such as an electrophotographic type printer or a facsimile includes a laser diode and a photosensitive drum. A plurality of selective driving circuits are provided for driving the laser diode, and at least one of the driving circuits is selected to form dot images having variable sizes on the photosensitive drum in accordance with a given data supplied by a computer. The driving circuits have different driving currents, and a smaller dot image is formed when a driving circuit providing a lower driving current is selected. Also, delay elements are provided to form a dot image at a delayed timing. The apparatus also has a smoothing function to correct jaggies in a picture.
