Abstract
A developing unit is provided, which includes: a developer carrier; a housing; and a side sealing member disposed between an end part of the developer carrier and a portion of the housing adjacent to a supply port. The side sealing member includes an elastic member having an integral base part attached to the portion of the housing and plural integral projections protruding from the base part toward the developer carrier in a protruding direction. A distal end part of each of the projection has an inclination face inclined so that a part of the inclination face is closer to the supply port as the part of the inclination face is farther from the base part in the protruding direction.
