摘要： Impurities contained in a developer are captured and prevented from mixing into the developer again, thereby to avoid lowering of image quality due to the impurities. Such impurities include aggregates of the developer formed in a developing apparatus, insufficiently charged toner particles, defectively charged toner particles having an opposite polarity to a predetermined polarity, and defective carrier particles lacking in strength for being held by a developing magnet roller. A recess is provided between peaks of magnetism located in a lower portion of a developing magnet roller. The recess has an air pressure substantially equal to an air pressure (atmospheric pressure) in the developing apparatus, so that air in the developing apparatus and the recess does not flow only in one direction. Impurities contained in the developer circulating around the developing roller cannot be magnetically held in the lower half of the developing roller because of centrifugal force and gravity. Consequently, the impurities are separated and collected in the recess.

摘要： The invention is characterized by efficiently and quickly loosening an aggregation of toner material formed in a toner cartridge. A toner cartridge has an L-shaped toner agitating member disposed in a main body thereof having a discharge port for feeding toner at the front surface of the main body. Since the toner agitating member is supported so as to pivot like a conical pendulum, a support pin fixed to a bottom surface of the main body passes through a through hole having a greater diameter than that of the support pin. The support pin has an engagement portion attached thereto for prevention of disengagement of the toner agitating member therefrom. A plate-like portion of the toner agitating member defines an agitating plate, a distal end of which extends toward the discharge port of the main body. Shaking the toner cartridge causes the agitating member to rotate about the support pin and to pivot in a direction parallel to the axis of the support pin like a conical pendulum, thereby efficiently loosening the aggregated toner material.
摘要翻译：本发明的特征在于有效且快速地松动形成在调色剂盒中的调色剂材料的聚集。调色剂盒具有设置在其主体中的L形调色剂搅拌构件，其具有用于在主体的前表面供给调色剂的排出口。由于调色剂搅拌构件被支撑成像圆锥摆一样枢转，所以固定在主体底面的支撑销通过直径大于支撑销直径的通孔。支撑销具有附接到其上的接合部分，用于防止调色剂搅拌部件脱离。调色剂搅拌构件的板状部分限定了搅拌板，其远端朝向主体的排出口延伸。摇动调色剂盒使得搅拌构件围绕支撑销旋转并且沿着平行于支撑销的轴线的方向像圆锥摆动一样地枢转，从而有效地松开聚集的调色剂材料。

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： Vents are formed on a developer flow regulating plate inside a casing so as to reduce a pressure in a first space which increases as a developer holder rotates. Further, vents for connecting a vacuum space formed in front of a developer layer thickness regulating section for regulating a thickness of a developer layer formed on the surface of the developer holder and the outside air are formed. The vents thus formed for connecting the vacuum space and the outside air take in the outside air along the front face of the developer layer regulating section so as to increase the negative pressure in the vacuum space. A shape of a lower edge portion of an opening section formed on the casing is varied in a longitudinal direction so as to optimize an effect of suppressing a scattering of a developer. Furthermore, a rotation start timing of an agitating section for agitating the developer to be supplied to the developer holder is delayed from a rotation start timing of the developer holder. The described features permit the scattering of the developer to be suppressed.
