Abstract:
A developing device includes a housing, a developing roller that carries developer, a supply roller for supplying the developer, a developer cartridge that accommodates the developer, a first sealing member that is provided at both ends of the developing roller, a developer passage opening provided in at least one of the housing and the developer cartridge, and a second sealing member provided in a vicinity of the developer passage opening. At least a part of the second sealing member overlaps the first sealing member in a direction in which the developer cartridge is attachable to and detachable from the housing. A portion of a shadow of the second sealing member cast in a direction, in which the developer passes through the developer passage opening, overlaps the first sealing member. The developer cartridge is attachable to and detachable from the housing at a position opposed to the developing roller.
