<p>A developer cartridge includes a developer storing portion (22,57) in which a developer is stored, a developer supplying portion (36,59) for supplying the developer to a main body (85) of an image forming unit, an opening-and-closing member (37,54) that opens and closes the developer supplying portion, an operating member (39,61) for operating the opening-and-closing member, and an engaging portion (81,55) engagable with a to-be-engaged portion (47) 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.</p> |
