Abstract
An improved electrostatic film-forming apparatus that employs a rubbing belt instead of a conventional roll brush is disclosed. The electrostatic film-forming apparatus is configured to deposit powder onto an object by electrostatic force. The electrostatic film-forming apparatus comprises: a screen having a mesh formed thereon; a rubbing belt configured to rub the powder into the screen; a pressing head configured to press the rubbing belt against the screen; a belt moving mechanism configured to move the rubbing belt in its longitudinal direction; a power source configured to apply a voltage between the screen and the object; and a hopper configured to supply the powder to the rubbing belt or the screen.
