CLEANING APPARATUS, CLEANING METHOD, PATTERN FORMING APPARATUS AND PATTERN FORMING METHOD

摘要

A pattern forming apparatus is provided with a drum-shaped engraved plate (1) which rotates along a medium to which a pattern is to be transferred. After the engraved plate (1) is electrostatically charged by an electrostatically charging apparatus, the engraved plate (1) is supplied with a liquid developer of each color by a developing apparatus to form a pattern by toner particles, the engraved plate (1) is rotated along the medium to form an electrical field between the engraved plate and the medium, and the electrostatically charged toner particles are transferred to the medium. A cleaning apparatus (8) transfers the pattern of each color to the medium, and then cleans the engraved plate (1). The cleaning apparatus is provided with nozzles (102, 103) having an angle for blowing a cleaning solution to the recessed portion, and removing rollers (104, 105) for removing toner particles released from the recessed portion with the cleaning solution.
