Abstract
PURPOSE: To certainly carry out developer feed and its stop in a simple mechanism, by stopping rotation of feed rollers in shifting developing to nondeveloping, and after a little while, stopping rotation of developing rollers.
CONSTITUTION: Developer 68 stirred with agitating member 62 and agitator 63 in the lower part of developing vessel 61 is carried upward with feed rollers 64, 65, transferred to second and first developing rollers 66, 67, and comes in contact with a latent image on a photoreceptor between both the rollers to develop the image. In shifting developing to nondeveloping in this developing unit, rotation of member 62, agitator 63, and each feed roller 64, 65 is first stopped, and a little while later, rotation of each developing roller 66, 67 is stopped. Such structure permits developer feed and its stop to be certainly carried out in a simple machanism.
