Pattern generation method by direct toner irradiation

A novel method for toner pattern generation is proposed. The image pattern is simply formed by direction of a light flash through a pattern mask to expose toner on a transparent support. The force of movement from light of which the optical energy density was 0.73 J/cm(2) and the exposure time was 0.43 ms FWHM was estimated to be more than 2.8 x 10(-9) N. The cause of the transfer was examined, and ablation of toner was determined to be the most likely. If this method can be applied to a printer, a simple process to form images may be realized.
