摘要： Disclosed is a developing process using a two-component type magnetic developer, where the main pole of developing magnetic poles in the developing sleeve is arranged upstream of the position, where a photosensitive drum becomes closest to the developing sleeve, in the rotation direction of the developing sleeve, this closest position between the drum and the developing sleeve is included in a region where the flux density in the magnetic force distribution of the main pole decreases toward the downstream side in the rotation direction of the sleeve, an alternating current voltage is applied between the developing sleeve and the drum to form an alternating electric field between the highest voltage and lowest voltage of the electrostatic latent image and in this state the development is carried out. According to this process, the conditions required for the supply of the developer are considerably moderated and an image having a high quality can be advantageously obtained.

摘要： A pair of indentations is formed with a vertical spacing on a side wall of a toner cartridge, respective translucent windows are arranged on opposing upper and lower surfaces of the indentations protruding into the toner cartridge, and a light-emitting element and a light-receiving element of a remaining toner sensor are inserted to the indentations such that the light-emitting element and the light-receiving element of the remaining toner sensor face each other via the translucent windows of the indentations. When there is sufficient toner remaining in the toner cartridge, there is toner in the space between the transparent plates, and the space between a light-emitting diode and a phototransistor is blocked such that light is not incident on the phototransistor, whereas when there is little toner remaining in the toner cartridge, there is no toner in the space between the transparent plates, and the light is incident on the phototransistor via the space between the light-emitting diode and the photoresistor.

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 document size detecting device with the arm which folds by interlocking with the reciprocating motion of the optical system of the image forming apparatus and extends and contracts by interlocking with the reciprocating motion of the optical system. The optical sensor for detection of the document size is installed at a prescribed position of the arm and the feeder line for the light source is held. Therefore, the special mechanism for holding the feeder line is not necessary and it is possible to achieve simplified construction of the image forming apparatus. Also, because the feeder line is caused to curve along the outside of the arm at the rotating section thereof, it is possible to provide a large radius of the bent portion of the feeder line, there will be no considerably concentrated stress which is locally applied to the feeder line, therefore the life of the feeder line can be extended.
摘要翻译：具有臂的文件尺寸检测装置，其通过与图像形成装置的光学系统的往复运动互锁而折叠，并且通过与光学系统的往复运动互锁而延伸和收缩。用于检测文件尺寸的光学传感器安装在臂的规定位置，并且保持用于光源的馈线。因此，不需要用于保持馈线的特殊机构，并且可以实现图像形成装置的简化结构。此外，由于使馈线在其旋转部分沿着臂的外侧弯曲，所以可以提供馈线的弯曲部分的大半径，将不存在局部施加的相当集中的应力到馈线，因此可以延长馈线的寿命。
