METHOD OF DEVELOPER SUPPLY CONTAINER PRODUCTION, DEVELOPER SUPPLY CONTAINER, DEVELOPING DEVICE, PROCESS CARTRIDGE AND IMAGE FORMING DEVICE Russian patent published in 2017 - IPC G03G15/18 

FIELD: image forming devices.

SUBSTANCE: present invention relates to developer supply container production method intended for use in image forming device, such as copier machine, printer and fax machine using electrophotographic printing method or electrostatic recording process, and to developer supply container, developing device, process cartridge and image forming device. Disclosed group of inventions includes developer supply container production method, developer supply container configured to contain developer, developing device, process cartridge, detachably mounted in image forming device main housing, and image forming device. At that, method of developer supply container production containing frame, configured to form part, containing developer, first electrode and second electrode, which is arranged on frame surface and which has surface arranged opposite to first electrode, wherein amount of developer in developer containing part is detected based on capacitive resistance between first electrode and second electrode, wherein method involves stages, at which: retaining element from conductive resin forming second electrode, on molding die, configured to form frame, wherein surface of element from conductive resin contacts with molding die surface, and molding die surface is configured for frame surface forming on developer containing part side, injecting resin, which must be formed into frame, into molding die, on which element from conductive resin is retained and performing resin curing to form frame, to which second electrode is attached, formed by means of element from conductive resin.

EFFECT: technical result consists in provision of developer supply container, developing device and process cartridge, which improve amount of developer detection accuracy by means of capacitive resistance detecting method, in case of use of elements from conductive resin for electrodes production.
