ABSTRACT:
A developing apparatus includes a roller-shaped developer carrying member, a frame for holding the developer carrying member, and a magnetic seal member for preventing leakage of a developer from an end of the developer carrying member in a longitudinal direction of the developer carrying member. The magnetic seal member includes an arcuate magnet portion to be disposed along a circumferential direction of the developer carrying member, and a non-arcuate portion which extends from an end, in the circumferential direction, of the magnet portion away from a peripheral surface of the developer carrying member and is different in material from the magnet portion.
