摘要： A developing device containing an initial developer in a sealed initial developer storage space sealed with a film and a magnetic toner in a sealed toner container is mounted on the frame of an electrostatic apparatus. Then, the film sealing the initial developer storage space and the toner container is removed to let the initial developer fall into an initial developer containing space near a developing sleeve and to let the magnetic toner fall into a space separated from the initial developer containing space by a partition wall. As the magnetic toner of the initial developer is consumed with the progress of printing operation, the toner flows through a gap defined by the partition wall into the initial developer containing space. The initial developer and the magnetic toner can be surely supplied to the developing sleeve simply by removing the film before using the developing device.

摘要： In an image forming apparatus has a photosensitive drum, the drum is charged by a main charger. A light beam bearing image information is applied to the drum by an exposure system to form a latent image on the surface of the drum. The latent image is developed by a developing unit, using a toner to form a toner image on the drum surface. The toner image is transfered to the surface of a paper sheet by a transfer charger. The developing unit serves to remove, simultaneously with the development of the latent image, the toner remaining on the drum surface after the transfer by the transfer charger. Before the removing of the remaining toner, the drum is in sliding contact with a brush member. The remaining toner is temporarily attracted to the brush member by the bias voltage applied to the brush member, with the result that the remaining toner becomes easy to separate from the drum. In the apparatus, the drum and at least the brush member are integrated as one process unit. The process unit is removably insertable into a predetermined operative position in the body of the apparatus. Accordingly, when the drum is removed from the operative position, the toner attracted to the brush member is prevented from scattering in the body by removing the brush member with the drum.
摘要翻译：在图像形成装置中具有感光鼓，滚筒由主充电器充电。通过曝光系统将支撑有光束的图像信息施加到滚筒，以在滚筒的表面上形成潜像。潜像由显影单元显影，使用调色剂在鼓表面上形成调色剂图像。调色剂图像通过转印充电器转印到纸张的表面。显影单元用于在转印充电器转印之后，与潜像的显影同时除去剩余在鼓表面上的调色剂。在除去剩余调色剂之前，滚筒与刷构件滑动接触。剩余的调色剂通过施加到刷构件的偏压暂时地吸引到刷构件，结果是剩余的调色剂容易与鼓分离。在该设备中，滚筒和至少刷子部件被集成为一个处理单元。处理单元可移除地插入装置主体中的预定操作位置。因此，当滚筒从操作位置移除时，通过用滚筒去除刷子部件来防止吸附到刷子部件的调色剂散射到主体中。

摘要： In a reproducing machine the photoconductive member, in the form of an endless belt, and the developing station are carried in a container or cartridge removably mounted on the machine. The photoconductive belt surrounds a support structure integral with the cartridge. The support structure includes a resilient portion engaging the photoconductive belt to keep it under tension around the structure. A magnetic belt of tubular form, fixed within the cartridge, is surrounded by a sleeve of non-magnetic material. The magnetic belt is so magnetized as to form a regular distribution of pairs of magnetic poles of opposite polarity. The toner adheres by magnetic action on the external surface of the sleeve to form a magnetic brush of the developing station.

摘要： In an image forming apparatus, a second shutter is caused to slide in conjunction with a first shutter which slides in the mounting direction in association with a mounting operation of a developing device to an apparatus body. Accordingly, in association with a separating movement of the developing device from the apparatus body, the first shutter is caused to slide in association with the second shutter which slides in the separating direction, which is the opposite direction from the mounting direction. The direction that the second shutter opens a discharge port is the same direction as the mounting direction. An urging force that a first urging member applies to the first shutter which closes an inlet port is smaller than an urging force that the second urging member is applied to the second shutter which closes the discharge port.
