摘要 |
A developing apparatus for developing a latent image formed on an electrophotographic photosensitive member, includes (a) a developer carrying member for feeding a magnetic developer to develop a latent image formed on the electrophotographic photosensitive member with the magnetic developer, wherein a magnet is disposed in the developer carrying member; (b) a magnetic seal member provided at each of one and the other longitudinal ends of the developer carrying member with a clearance from a peripheral surface of the developer carrying member to prevent leakage of the developer in a longitudinal direction of the developer carrying member; (c) a developer regulating member provided contacted to the peripheral surface of the developer carrying member to prevent reentering of the developer having passed through the gap between the developer carrying member and the magnetic seal member.
