To provide an image formation apparatus capable of preventing wrong detection due to biasing of a developer without unnecessarily crushing the developer.SOLUTION: An image formation apparatus comprises: a developer storage part 50 which stores a developer; a rotary shaft 60 which is provided in the developer storage part 50; a drawn part 61 which is drawn in a drawing direction E from the rotary shaft 60 toward an inner side face of the developer storage part 50; a developer amount detection part 70 which detects the amount of the developer in the developer storage part 50; a detection plate 90 which passes within a detection range KR of the developer amount detection part 70; and a flexible member 80 which is fitted to the drawn part 61 and flexes as the rotary shaft 60 rotates. The drawn part 61 has a sticking surface along a crossing direction H crossing the drawing direction E. The flexible member 80 has its root part stuck on the sticking surface, and is fitted with the detection plate 90 at a front end part.SELECTED DRAWING: Figure 5 【課題】現像剤を必要以上に押しつぶすことなく、現像剤の偏りによる誤検知を防ぐことができる画像形成装置を提供する。【解決手段】画像形成装置は、現像剤を収容する現像剤収容部５０と、現像剤収容部５０内に設けられた回転軸６０と、回転軸６０から、現像剤収容部５０の内側面に向かう延伸方向Ｅへ延伸された延伸部６１と、現像剤収容部５０内の現像剤の量を検知する現像剤量検知部７０と、現像剤量検知部７０の検知範囲ＫＲを通過する検知板９０と、延伸部６１に取り付けられ、回転軸６０の回転に応じて撓む可撓性部材８０とを備える。延伸部６１は、延伸方向Ｅと交差する交差方向Ｈに沿った張付面を有する。可撓性部材８０は、根元部が張付面に張り付けられ、先端部に検知板９０が取り付けられている。【選択図】図５
