Abstract
An electrostatic coating device and an electrostatic coating method each achieve a reduction in working hours and efficient coating at the time when layers are coated with colors. The electrostatic coating device includes a coating material cartridge that includes coating-material containers, a valve that makes a change of colors of coating materials, a common path through which coating materials are able to pass according to the change, and a cleaning circuit that cleans up the common path. The coating material cartridge is configured to be removable from a coating machine. The coating material cartridge may include individual paths respectively connected to the coating-material containers and each of which one of the coating materials passes through, and valves each connected to the common path and respectively connected to the individual paths. Each of the valves may open and close a conduit line between the common path and a corresponding coating-material container.
