Abstract
A wet-type image forming device includes a development roller, a squeeze roller, a cleaning roller, a brush roller, and a reservoir, with voltages being applied to these components. A portion of one side of the reservoir is bent in a V-shape to form a protrusion so as to scrape toner particles from the brush roller. Toner particles adhering to the cleaning roller are mostly removed therefrom to sequentially adhere to the brush roller by a potential difference between the cleaning roller and the brush roller, and by opposing rotation of the cleaning roller and the brush roller in contact therewith. Toner particles remaining on the cleaning roller are scraped off by a cleaning blade to also adhere to the brush roller. Toner particles adhering to the brush roller are scraped off by the protrusion of the reservoir and are then dispersed in the liquid developer within the reservoir.
