摘要： A movable frame is mounted on a stationary frame so as to be reciprocatingly moved in a predetermined direction by a moving means. The movable frame is equipped with a plurality of developing mechanisms which may be selectively located at a developing position by the motion of the movable frame to carry cut multi-color developing. The developing mechanisms are urged toward a rotary drum. In order to prevent the developing agent from scattering, side sealing pieces are provided near the non-developing operation region on both sides of a sleeve member in a magnetic brush mechanism of each developing mechanism. A toner container unit including toner containers and toner feeding means is rotatably supported by the stationary frame. The toner feeding means includes a extensible and contractible means which is detachably coupled to the developing mechanism. The toner container unit is selectively brought to a predetermined fixed position relative to the developing mechanism and to a predetermined retracted position turned in a direction to separate away from the developing mechanism.

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.
