Developing device

A developing device comprising:

• a developing roller;
• a frame body having an accommodating portion for accommodating developer to be borne on the developing roller, the frame body is formed of an insulating resin;
• and
• a first conductive portion and a second conductive portion integrally molded by injecting a conductive resin into the frame body,
• wherein the first conductive portion includes a first electrode portion and a first electrical contact portion, the first electrode portion being exposed in the accommodating portion, the first electrical contact portion being electrically connected to the first electrode portion and being exposed outside the accommodating portion,
• wherein the second conductive portion includes a second electrode portion and a second electrical contact portion, the second electrode portion being exposed from the frame body inside the accommodating portion, the second electrical contact portion being electrically connected to the second electrode portion and being exposed from the frame body outside the accommodating portion,
• wherein the first electrode portion and the second electrode portion are disposed so as to face each other with a space therebetween and are configured to function as a capacitor when a voltage is applied between the first electrical contact portion and the second electrical contact portion.
