摘要:
An image forming apparatus includes a reservoir base section with a recess that receives liquid developer scraped off of a developing roller by a cleaning blade. The recess is substantially U-shaped with an opened top side and an arc angle of not less than 180°. A conveying base station is continuous with the reservoir base section and has a conveying port formed thereon. A conveying member arranged in the reservoir and conveying base sections conveys liquid developer through a hollow path from the recess to the conveying port by rotating about its axis. The radius r1 of the outer periphery of the conveying member, the radius r2 of the conveying port and the radius r3 of curvature of the recess have the relationship r1
