The developing device comprises a developer agitation-transfer means, a developer roller, a developer feeding roller, a developer guide member and a space forming member. The developing device is characterized in that the developer feeding roller rotates to transfer the developer transferred by the agitation-transfer means, upward from the clearance between the developer feeding roller and the developer guide member, and in that, when the developer standby space formed in the device is filled with the developer transferred by the developer feeding roller, the developer feeding roller is rotated to carry the developer, which overflows from the developer standby space, and to move the same in the direction away from the developer roller, so that the developer is once discharged from the developer standby space.</p> |
