Abstract

PURPOSE:To restrain nonuniformity in potential in marginal area and reduce dot loss in electrostatic latent images per dot pulse, by causing a transferring means for transferring image data to a light beam scanning means to transfer the image data on a line basis to the light beam scanning means at a speed two times the speed of acquiring data from a host device, and sweeping a light beam twice for each one-line amount of data inputted. CONSTITUTION:When data on the n-th line in VDATA is written into a line memory 25, data for the (n-1)th line is read from a line memory 26 to a line memory reading-controlling part 27 two times successively. When the data for the n-th line is read from the line memory 25 to the reading-controlling part 27, data on the (n+1)th line is written into the line memory 26. By repeating these operations, a controlling circuit 21 takes in a one-line amount of data at an ordinary scanning density (240dpi) from a host computer 30, and stores the data into each of the line memories 25, 26, while transferring a one- line amount of data from the reading-controlling part 27 to a laser beam scanning unit 20 at 480dpi in only an auxiliary scanning direction.
