Abstract
A sheet coating apparatus including a storage tank in which a coating liquid having charged coating particles dispersed therein is contained, a development roller rotatably installed to be immersed in the coating liquid, a voltage source for applying a voltage to the development roller, a coating roller rotatably installed in a state in which it is partially immersed in the coating liquid while maintaining a predetermined development gap relative to the development roller, and a compression roller for pressing a sheet passing between the compression roller and the coating roller toward the coating roller while securely rotating with respect to the coating roller. The coating particles adhere to the surface of the coating roller at the development gap due to an electric force to then be coated on the sheet passing between the coating roller and the compression roller. The sheet coating apparatus can prevent excess coating liquid from being coated on a sheet by regulating the amount of the coating liquid coated on the sheet, thereby attaining uniform coating.
