摘要： The length of a conveying sheet is set to be greater than the rotational radius of an agitating element so that the distal end of the conveying sheet will slide over the inner wall of the toner container. A slider element having a low frictional resistance is attached at the distal end of the conveying sheet. The slider element preferably has a low coefficient of dynamic friction and is preferably made of a soft resilient material having a thickness smaller than the conveying sheet. Cutouts or openings may be preferably formed at the distal part. A multiple number of ribs are attached to the wall surface of the toner container at the highest position at which the wall and the top plate meet. The ribs are arranged apart from each other in the direction parallel to the agitating shaft of the agitating element. Each rib is a plate-like element projected inward from the wall surface in the toner container with its width put in the direction of the spacing. Further the end portions of the ribs on the interior side of the toner container are adapted to form a curved surface smoothly connecting the top plate surface and the wall surface.

摘要： A developing unit includes a developer hopper, a toner reserve container that incorporates a replenishing roller and a replenishing opening forming a toner replenishing portion, arranged adjacent to the developer hopper in order to replenish the toner to the developer hopper. The toner reserve container further includes an agitator rotatable about a rotary shaft with a conveying sheet for conveying the toner to the replenishing roller. The conveying sheet is attached to the agitator so that it becomes close to the rotary shaft of the agitator. By this configuration, an adequate space can be secured between the top plate, i.e., an operable/closable lid, constituting the toner reserve container and the conveying sheet so that the distal part of the conveying sheet can efficiently retain the toner, thus making it possible to improve the conveyance performance to the replenishing roller and realize an uniform amount of conveyance.

摘要： A developing unit includes a developing hopper, a toner reserve container that incorporates a replenishing roller and a replenishing port forming a toner replenishing portion, arranged adjacent to the developing hopper in order to supply the toner to the developing hopper. The toner reserve container further includes an agitator rotatable about a rotary shaft and a conveying sheet attached to the agitator for conveying the toner to the replenishing roller. The conveying sheet has a bent portion where the conveying sheet is bent in the rotational direction of the agitator at a halfway point thereof with a predetermined angle &agr;. Deformation of the conveying sheet during rotation is absorbed around the position of the bent portion, so that the conveying sheet will not be plastically deformed at the attached part of the conveying sheet joined to the attachment edge of the agitator, whereby long stable toner conveyance by the conveying sheet can be maintained.

摘要： A developer cartridge capable of being fitted to the toner replenishing opening of a developer storage hopper has a sealing member for sealing the toner therein that is bonded to the rim of its replenishing opening to be opposed to the opening of the developer storage hopper. The bottom face of this developer cartridge which constitutes the bottom for supporting the toner stored therein is inclined upwards in the stripping direction of the sealing member, whereby the supplied amount of the toner at the stripping start of the sealing member is regulated when the sealing member is stripped so that the toner can be uniformly supplied across the full length of the developer storage hopper with respect to the stripping direction of the sealing member.

摘要： An image apparatus includes a cartridge with two separate accommodating portions. The first accommodating portion for accommodating unused developer and is formed in a housing. A second accommodating portion for accommodating transfer residual developer is arranged adjacent to the first accommodating portion. A conveying member extending over the first and second accommodating portions, when an amount of transfer residual developer to be stored in the second accommodating portion exceeds a predetermined level, conveys the transfer residual developer from the second accommodating portion to the first accommodating portion. Each one of the accommodating portions includes an agitator.

摘要： A developing apparatus is equipped with a development casing, a development roller, and developer stirring shafts that rotate together with the development roller. In this developing apparatus, the developer stirring shafts are disposed adjacent to each other and are also disposed substantially in parallel with the development roller. Each developer stirring shaft has a rotational axis that rotates together with the development roller and has a plurality of stirring vanes of an approximately elliptic shape laid out at a predetermined angle with respect to the rotational axis. The rotational axis is provided substantially in parallel with the development roller. The stirring vanes are disposed substantially in parallel with each other, with the opposing stirring vanes between the adjacent developer stirring shafts having mutually different installation positions in the axial direction.
