Abstract
An intermittent ejection processing unit detects a driving state of at least one of driving motors of a developing agent conveying member and a stirring member which are driven at a predetermined rotational speed when a developing agent is ejected and intermittently makes each driving motor operative until a detection value of the driving state decreases to a specified value, thereby intermittently ejecting the developing agent. A continuous ejection processing unit continuously makes each driving motor operative at a predetermined rotational speed after the detection value of the driving state of at least one of the driving motors was below the specified value, thereby continuously ejecting the developing agent, and finishes the ejection of the developing agent when the detection value of the motor driving state decreases to a specified value corresponding to a no-load state by the completion of the ejection of the developing agent.
