At this time, the developer dripping generated during the upper spraying will be blocked and collected by the collecting plate, reducing the damage problem caused by high dripping to the first nozzle position;

[0016] (3) The developer is introduced into the feed port, and the driving motor is started to drive the mixing rod to rotate. The developer is fully mixed by the mixing rod.
