<P>PROBLEM TO BE SOLVED: To provide a sensor device being applicable regardless of the shape of a developer container and capable of improving measuring accuracy of the amount of developer and noise resistance in the sensor device for detecting an amount of powder to fill a container. <P>SOLUTION: For achieving the purpose, the sensor device according to the present invention includes a configuration that parts of detection electrode parts 22 and 23 are pulled out to the surface of a housing 31 and joined to the surface thereof so as to expose at least the parts of the detection electrodes 22 and 23 to the surface of the housing 31. A detecting part 21 is configured from a PPS (polyphenylene sulfide) film having different melting points in the thickness direction. In the detecting part 21 having pulled out to the surface of the housing 31, a low-melting-point side of the PPS film is joined with the housing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
