PROBLEM TO BE SOLVED: To provide a developer container configured to detect the amount of developer in the container accurately.SOLUTION: A developer container includes: a frame body 18 for storing developer; and a conductive sheet 24 having conductivity and comprising a first exposure unit 24b which exposes an inside surface of the frame body, a penetrating part 24c extending from the first exposure unit 24b and passing through a wall part of the frame body 18, and a second exposure unit 24a extending from the penetrating part 24c to be exposed to an outside surface of the frame body 18 and arranged in a position not overlapping the first exposure unit 24b in a thickness direction of the wall part. The second exposure unit 24a is configured so that a thickness of an area corresponding to the end of the conductive sheet 24, of the area including the end of the conductive sheet 24 and corresponding to the second exposure unit 24a of the conductive sheet 24, in the wall part of the frame body 18, is larger than the thickness of the other area apart from the end.SELECTED DRAWING: Figure 7 【課題】容器内の現像剤量を精度よく検出することができる現像剤容器を提供する。【解決手段】現像剤を収容するための枠体１８と、導電性を有し、枠体の内側の表面に露出する第１露出部２４ｂと、第１露出部２４ｂから延びて枠体１８の壁部を貫通する貫通部２４ｃと、貫通部２４ｃから延びて枠体１８の外側の表面に露出し且つ壁部の厚み方向において第１露出部２４ｂと重複しない位置に配置される第２露出部２４ａと、を備える導電性シート２４と、を有し、第２露出部２４ａは、導電性シート２４の端部を含んでおり、枠体、１８の壁部において、導電性シート２４の第２露出部２４ａに対応する領域のうち、導電性シート２４の端部に対応する領域部分の厚さは、端部から離れた他の領域部分の厚さよりも大きい。【選択図】図７
