囲第１項記載の現像装置。[Claims for Utility Model Registration] 1. The two- component developer drawn up by the first developing roller is transferred to the second developing roller to perform development, and after the development, the developer remaining on the second developing roller is removed. In the developing device in which the first developing roller is returned again to perform a reproduced image, at a developer delivery portion between the first developing roller and the second developing roller,
A developing device comprising a developer guide plate that prevents developer from going around to a first developing roller. 2. Registration of a utility model characterized in that the developer guide plate is installed so as to regulate the developer inside the tangent to the point where the magnetic Gauss value becomes 0 in the developer delivery portion of the first developing roller. A developing device according to claim 1.
