登録請求の範囲第１項記載の現像装置。[Scope of Claim for Utility Model Registration] 1. The excess amount of the developer that is stirred by the stirring roller, adsorbed by the developing roller, and transported to the developing section of the photosensitive drum is scraped off by the developer regulating means, and the developer is rectified. In a developing device configured to be returned to the stirring roller by a guide plate having a rectifying plate for the purpose of the present invention, in order to attach the rectifying plate to the guide plate, a mounting base of the rectifying plate has a direction in the axial direction of the developing roller. A developing device characterized in that the width in the direction along the developer is small at an upstream end in the developer flow direction and becomes larger toward the downstream side in the developer flow direction. 2. The end portion of the mounting base of the current plate along the developer flow direction is formed at a predetermined angle with respect to the developer flow direction in the same direction as the end face of the current flow plate is inclined with respect to the developer flow direction. The developing device according to claim 1, wherein the developing device is attached to the guide plate so as to maintain the same.
