To provide an image formation device capable of preventing occurrence of jamming of a paper sheet caused by erroneous determination of a paper kind.SOLUTION: A printing condition suitability determination part 106, in requesting printing of an image, determines whether or not a printing condition determined by a user is suited for conveyance of an envelope. A paper processing decision part 107, when the printing condition determined by the user is not suited for conveyance of the envelope, does not cause a printing part to perform processing for the envelope regardless of a detection result of an ultrasonic sensor 117. Instead, as occurrence of double feeding, conveyance of a paper sheet is stopped.SELECTED DRAWING: Figure 3 【課題】用紙種別の判定を誤ることによる、用紙のジャム発生を防止することができる画像形成装置を提供する。【解決手段】印刷条件適合判定部１０６は、画像の印刷を要求するにあたって、ユーザーが定めた印刷条件は、封筒の搬送と適合するかどうかを判定する。用紙処理決定部１０７は、ユーザーが定めた印刷条件が封筒の搬送と適合しない場合、超音波センサー１１７の検出結果にかかわらず、封筒を対象とした処理を印刷部に行わせない。代わりに、重送が発生したとして、用紙の搬送を停止する。【選択図】図３
