Abstract

PURPOSE:To prevent uneven print, by providing a detection means which detects the density of document information and a means which controls the flashing time of a flash lamp corresponding to the density of a document information detected through the detection means. CONSTITUTION:Electrostatic creep image is formed for an electrostatic recording paper 11 delivered from a recording paper stacker 11 at a multistylus electrode 12. The paper 11 is electrostatically printed for the carrier storainer 14 at a developing section with a magnetic brush development system, a flash lamp 17 is illuminated at a flash printer, the optical energy is absorbed to toner to heating and melt the toner so that is can be printed on a recording paper. In this case, the absorbed light amount per unit area of the black part of the print surface is kept constant to prevent uneven print and the power consumption can be reduced by suitable power supply according to the black area rate.
