摘要:
In a developer amount successively indicating method used in an electrophotographic image forming apparatus capable of detachably mounting a plurality of types of cartridges differing in the fill amount of a developer, an indicating portion selected in conformity with the type of one of the plurality of types of cartridges which is mounted in the main body of the electrophotographic image forming apparatus is indicated, and the detected amount of developer in the cartridge mounted in the main body of the electrophotographic image forming apparatus is successively indicated by the use of the indicating portion.
摘要:
A developing device includes a developer container which is mountable to an electrophotographic image forming apparatus main body, contains a developer for developing an electrostatic latent image formed on an electrophotographic photosensitive member, and includes a developer bearing member for carrying the developer to the electrophotographic photosensitive member, and a plurality of developer remaining amount detectors for successively detecting the remaining amount of developer within the developer container, wherein regions detected by the plurality of developer remaining amount detectors are overlapped with each other, and in the overlapped regions, a detected value by a previous developer remaining amount detector is changed over to a detected value by a succeeding developer remaining amount detector, and the apparatus main body detects the detected value to detect the remaining amount of developer.
摘要:
An electrophotographic image forming apparatus for forming an image on a recording medium includes an electrophotographic photosensitive member, an electrostatic latent image forming device for forming an electrostatic latent image on the electrophotographic photosensitive member, a developing device for developing the electrostatic latent image formed on the electrophotographic photosensitive member, a developer remaining amount detecting device for successively detecting the remaining amount of developer to be used for the development of the electrostatic latent image by the developing device, and a developer remaining amount indicating device for indicating the remaining amount of developer detected by the developer remaining amount detecting device. The developer remaining amount indicating device indicates the remaining amount of developer as a gauge and indicates it with graduations shown on the gauge that are changed over in conformity with the remaining amount of developer.
摘要:
A process cartridge includes a first frame in which a toner containing unit for containing toner used for a developing operation and a charger unit are mounted, and a second frame which can be engaged by and disengaged from the first frame, and in which an image bearing member, a developing unit and cleaning unit are mounted. With this arrangement, the assembling ability and disassembling ability are improved remarkably, and the process cartridge is suitable for the re-cycling to contribute to the protection of the earth-environment.

摘要:
A process cartridge detachably mountable to an image forming apparatus includes a device contributable for forming an image; a developer accommodator; and a sealing member between the image forming device and the developer accommodator, wherein the sealing member is provided by injecting a liquid material which becomes an elastomer when it is solidified.
摘要:
A developing device includes a developer container containing magnetic particles; a developer holding unit formed at an opening portion of the developer container, the developer holding unit rotating while holding a developer; a magnetic field generating unit placed in the developer holding unit; a magnet placed along a circumferential direction of the developer holding unit to form a magnetic seal between the magnet and the developer holding unit; and a magnetic unit placed to be adjacent to the magnet. The developing device attains a reduction in driving torque and a high magnetic sealing performance.
