An image printing device includes a latent image charge keeping medium including a pyroelectric layer, a thermal head for selectively heating the charge keeping medium according to a signal, and an electrically conductive film disposed to be brought into contact with or to be in the vicinity of a surface of the pyroelectric layer of the medium for being heated by the thermal head, thereby neutralizing charge appearing on the medium due to pyroelectric effect. The device further includes a developer for visualizing with a charged coloring medium an electrostatic latent image formed on the medium, a transfer roller for transferring the developed image onto a sheet of printing paper, and a fixing device for fixing the transferred image on the printing sheet. The conductive layer is applied with a bias voltage from a power source such that a strong absorbing force acts upon charge, thereby efficiently neutralizing the charge. There are attained a high printing density and a favorable uniformity in the printing density.
