又は第２項に記載の現像装置。[Claims for Utility Model Registration] (1) A developing roller disposed opposite to the image carrier;
The developing roller has a blade member that contacts the developing roller from below, and an elastic means that presses the blade member in the direction of contacting the developing roller, and is configured to control the amount of toner that adheres to the developing roller by the blade member. In the developing device, a cover member is provided that straddles between the frame of the developing device main body and the side surface of the blade member and prevents toner from entering the lower part of the blade member, and the cover member prevents toner from entering the developing roller. The developing device is arranged on one side of the blade member facing the supply side. (2) According to claim 1 of the utility model registration claim, one end of the cover member is attached to the bottom plate of the main body of the developing device, and the other end is arranged so as to contact the side plate of the blade member. The developing device described. (3) The developing device according to claim 1 or 2, wherein the cover member is made of an elastic sheet. (4) The developing device according to claim 1 or 2, wherein the cover member is made of foam material.
