Abstract

PURPOSE: To extend the effective life of developer and improve the agitation efficiency, by specifing the storing and agitating method of developer.
CONSTITUTION: A developer well 16 is formed in the lower end part of a scraper 15, and a first agitating member 17 is disposed. A developer well 20 is formed in part of the developer moving route in the lower part of a developer container 10, and a second agitating member 21 is disposed. As a result, the developer D to be replenished with toner from a toner replenishing device 23 is pumped up onto a developing roller 11, and is controlled by a doctor plate 14, and a latent image on a photosensitive drum 8 is developed. Afterwards, when the developer is scraped by the scraper 15 onto the developing roller 11 and is returned to the lower part of the developer container 10, the developer D after developing is properly stored in the developer wells 16, 20 while it is gathered in the central part by means of the first agitating member 17, and is spread to both sides by means of the second agitating member 21, so that it may be agitated efficiently without using unreasonable force.
