ABSTRACT:
The invention relates to a selective particle applying device provided with a developer applying device. The selective particle applying device applies a developer to the entire surface of a capsule sheet coated with microcapsules, disposes the capsule sheet with its surface coated with the developer facing a developer removing electrode provided with a photoconductive member to which a predetermined voltage is applied, splits a light beam by a light beam splitter, irradiates the developer removing electrode with one of the split light beams, and irradiates the capsule sheet with the other split light beam. Portions of the photoconductive member irradiated intensely with the split light beam become conductive to enhance the intensity of electric fields created between conductive portions of the developer removing electrode and the capsule sheet. Consequently, the developer coating portions of the capsule sheet, corresponding to the conductive portions of the developer removing electrode, are drawn to the developer removing electrode to leave the developer only in portions of the capsule sheet necessary for forming an image.
