Abstract
This invention provides a new and improved image-forming apparatus which is of relatively easy manufacture and which provides a clear, sharp image. This apparatus is an 'ink jet' printer which utilizes a liquid dispersion of toner as the image-forming material. The liquid dispersant is dielectric relative to the toner particles. The toner particles agglomerate when placed under an electric charge and these agglomerated particles are ejected in accordance with an image signal. The toner forms an image on an image holder which is transferred to a recording medium such as paper. This invention has the provision for four-color printing.
