Summary:To provide a technique that can accurately detect a sheet around a cutter.SOLUTION: A printer 1 comprises: an apparatus body 2 that has a conveyance path 201 of a sheet S; a fuser 6 that has a heating roller 61, and fixes an image formed on the sheet S to the sheet S; a first ejection roller 85 that is located on the downstream side of the fuser 6 and conveys the sheet S; a second ejection roller 86 that is located on the downstream side in the conveyance direction of the first ejection roller 85 and ejects the sheet S conveyed by the first ejection roller 85 to the outside of the apparatus body 2; a cutter 10 that is located at a cutter position B being a position between the first ejection roller 85 and the second ejection roller 86 in the conveyance direction, and can cut the sheet S in a cut direction intersecting the conveyance direction; and a sheet detection sensor SE4 that detects whether the sheet S is present at a first detection position between the first ejection roller 85 and the second ejection roller 86 in the conveyance direction.SELECTED DRAWING: Figure 1 【課題】カッター周辺においてシートを精度よく検知することが可能となる技術を提供する。【解決手段】プリンタ１は、シートＳの搬送経路２０１を有する装置本体２と、加熱ローラ６１と、シートＳに形成された画像をシートＳに定着させる定着器６と、定着器６よりも下流側に位置し、シートＳを搬送する第１排出ローラ８５と、第１排出ローラ８５よりも搬送方向における下流側に位置し、第１排出ローラ８５により搬送されたシートＳを装置本体２の外部に排出する第２排出ローラ８６と、搬送方向における第１排出ローラ８５と第２排出ローラ８６との間の位置であるカッター位置Ｂに位置し、搬送方向と交差する切断方向にシートＳを切断可能なカッター１０と、搬送方向における第１排出ローラ８５と第２排出ローラ８６との間の第１検出位置にシートＳが存在するか否かを検出するシート検知センサＳＥ４と、を備えることを特徴とする。【選択図】 図１
