An image forming apparatus receives halftone print data through an inputting section (31, 32, 33). A dot forming section (36, 37, 38, 39, 12) irradiates the charged surface of an image bearing body with light to form a plurality of lines of dots in accordance with the halftone data. Dots on a same line have the same exposure energy and dots on different lines in a same pixel have different exposure energies. The plurality of lines (0 to(n-1), 0 to (s-1)) may include as many lines as there are bits in the halftone print data. The plurality of lines may include a first predetermined number of lines and the halftone print data includes a second predetermined number of bits different from the first predetermined number. A conversion table (41) converts halftone print data having a first number of bits into corresponding energy data having a second number of bits. |
