PROBLEM TO BE SOLVED: To make it possible to improve the accuracy of a result of detection of a toner residual amount.SOLUTION: An image forming apparatus comprises: a first acquisition part A that acquires a residual amount A by subtracting a consumption ΔA from a residual amount A1; a second acquisition part that acquires, as a residual amount B, the amount of developer remaining in a developer container after a previous or current image forming operation is executed; and a notification part that notifies a user of the residual amount A. When residual amount A1>residual amount B, the first acquisition part acquires the residual amount A by performing correction to increase the consumption ΔA, and when residual amount A1<residual amount B, acquires the residual amount A by performing correction to decrease the consumption ΔA.SELECTED DRAWING: Figure 4 【課題】トナー残量の検知結果の精度を向上させることができる。【解決手段】残量Ａ１から消費量ΔＡを減じて残量Ａを取得する第１取得部Ａと、前回または今回の画像形成動作が実行された後に現像剤容器内に残る現像剤量を残量Ｂとして取得する第２取得部と、残量Ａをユーザーに報知する報知部と、を有し、第１取得部は、残量Ａ１＞残量Ｂである場合に、消費量ΔＡを大きくする補正を行って、残量Ａを取得し、残量Ａ１＜残量Ｂである場合に、消費量ΔＡを小さくする補正を行って、残量Ａを取得する。【選択図】図４
