する現像装置のシール機構。[Claims for Utility Model Registration] 1. A seal for a developing device comprising a flocked seal member whose bristles are in contact with the outer peripheral surface of both ends of the developing roller so as to prevent toner leakage at both ends of the developing roller. In the mechanism, the flocked hair in the flocked seal member has an extending direction from the root to the tip side that forms a predetermined angle in the axial direction with respect to the radial direction of the developing roller, and the raised hair is located at the center of the developing roller. A sealing mechanism for a developing device, characterized in that it is set in a direction in which it collapses to the side. 2. In the sealing mechanism of the developing device according to claim 1, the axial inclination angle of the flocked hair in the flocked sealing member with respect to the radial direction of the developing roller is set to be 5° to 60°. The sealing mechanism of the developing device is a feature. 3. In the sealing mechanism of the developing device according to claim 1, the weaving angle of the flocking in the flocking sealing member is set to be 5° to 60° with respect to the circumferential direction of the developing roller. A sealing mechanism for a developing device characterized by the following.
