Latest Patents
Masatoshi Maruta holds 1 patent for a developing apparatus. This apparatus includes a hopper that stores toner and carrier, along with a roller positioned in an opening of the hopper. A carrier stopper is strategically placed on the front wall of the hopper, near the opening, featuring an arced surface that opposes the upper portion of the roller. This design creates a blend layer volume in a first space between the carrier stopper and the roller, which effectively stores a blended layer of carrier and toner. The carrier stopper prevents the carrier from scattering outside the blend layer volume, while the combination of the roller's rotation and the magnetic force of the rotary magnets blends the carrier and toner. Additionally, a sub-hopper is formed by a second space between the carrier stopper and a lateral bottom wall of the hopper, which stores toner to be provided to the blended layer.
