  • DEVELOPER CONTAINER, DEVELOPING APPARATUS, PROCESS CARTRIDGE, APPARATUS MAIN BODY, AND IMAGE FORMING APPARATUS
    Publication number: 20160223950
    Abstract: A developer container includes: a housing chamber 147 which includes an opening 145 and which houses developer; a stirring member 160 which includes a sheet-like stirring portion 160b and a rotary shaft 160a to which the stirring portion 160b is attached; and a first electrode 143 and a second electrode 144 which are used to detect an amount of the developer and which are arranged with an interval therebetween, where in an area X1 between the first electrode 143 and the second electrode 144 in the housing chamber 147 is positioned below the rotary shaft 160a of the stirring member 160, and the sheet-like stirring portion 160b comes into contact with the area X1 due to rotation of the stirring member 160.

  • METHOD OF MANUFACTURING DEVELOPER CONTAINER
    Publication number: 20160091821
    Abstract: A method of manufacturing a developer container including a frame configured to define a developer containing portion, a first electrode, and a second electrode 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 constituting the second electrode on a mold configured to mold the frame, a surface of the conductive resin member being in contact with a surface of the mold configured to mold a surface of the frame on a side of the developer containing portion; injecting a resin to be formed into the frame, into the mold on which the conductive resin member is held; and curing the resin to form the frame to which the second electrode is fixed.
