Summary:To provide an image forming apparatus that, even when changing an operation condition to a condition suitable for the water absorption of a sheet, prevents it from taking time from an instruction for image formation to the start of an image forming operation.SOLUTION: It is determined as to whether a paper feed cassette 12 is attached to an attachment position from a capacitance value C detected from an output signal from a capacitance detector 42, and after the paper feed cassette 12 is attached to the attachment position, the water absorption of a sheet P supported by a platen 13 is obtained according to input of an image forming instruction.SELECTED DRAWING: Figure 1 【課題】動作条件を用紙の吸水率に適した条件に変更する場合であっても、画像形成の指示から画像形成動作を開始するまでに時間がかかることを抑制できる、画像形成装置を提供する。【解決手段】静電容量検出器４２の出力信号から検出される静電容量値Ｃから、給紙カセット１２が装着位置に装着されているか否かが判定されて、給紙カセット１２が装着位置に装着された後、画像形成指示の入力に応じて、圧板１３に支持されている用紙Ｐの吸水率が求められる。【選択図】図１
