装置。 In a developing device used in an electrophotographic apparatus, after forming a magnetic brush that is rotatable for development, a seal roller is rotatably disposed in contact with the surface of the magnetic brush before development, and the seal roller is rotatably arranged in the axial direction of the seal roller. The tip of a blade made of film is pressed against the surface, and the seal roller and the blade isolate the inside of the developing device from the outside air, and a seal roller is placed opposite to the surface of the magnetic brush after development. The seal roller is rotatably arranged, and the tip of a blade made of a film is brought into pressure contact with the axial surface of the seal roller, and the seal roller and the blade can isolate the inside of the developing device from outside air. A developing device characterized by:
