ABSTRACT:
A developer cartridge includes a developer storing portion in which a developer is stored, a developer supplying portion for supplying the developer to a main body of an image forming unit, an opening-and-closing member that opens and closes the developer supplying portion, an operating member for operating the opening-and-closing member, and an engaging portion engagable with a to-be-engaged portion formed on the main body of the image forming unit. The opening-and-closing member takes one of an opening position where the opening-and-closing member opens the developer supplying portion and a closing position where the opening-and-closing member closes the developer supplying portion, when the engaging portion engages the to-be-engaged portion. The opening-and-closing member takes the closing position where the opening-and-closing member closes the developer supplying portion, when the engaging portion disengages from the to-be-engaged portion.
