Developer container, developing apparatus, process cartridge, and image forming apparatus

摘要

A method of manufacturing a developer container (4) including a frame configured to define a developer containing portion (46a), a first electrode (41), and a second electrode (43) arranged on a surface of the frame and having a surface opposed to the first electrode, a developer amount in the developer containing portion being detected based on a capacitance between the first electrode and the second electrode, the method including: holding a conductive resin member (43) constituting the second electrode on a mold (201) configured to mold the frame (40A), a surface of the conductive resin member (43) being in contact with a surface of the mold (221) configured to mold a surface of the frame on a side of the developer containing portion (40A); injecting a resin to be formed into the frame (40A), into the mold (201) on which the conductive resin member (43) is held; and curing the resin to form the frame to which the second electrode is fixed.
