IMAGE FORMATION DEVICE AND CONTROL PROGRAM

To automatically perform image formation adaptively to conveyance properties of even a recording medium in use which does not satisfy product specifications.SOLUTION: An image formation device 10 comprises: a first determination unit 111 which determines the kind of a recording medium based upon sheet physical properties that a media sensor 18 measures; a second determination unit 112 which determines conveyance performance for a recording medium conveyed in a conveyance path 143; and an image formation determination unit 113 which determines whether to perform image formation based upon the conveyance performance that the second determination unit 112 determines when the kind of the recording medium that the first determination unit 111 determines does not satisfy product specification.SELECTED DRAWING: Figure 2 【課題】製品仕様外の記録媒体が用いられる場合であっても、その搬送性能に応じた画像形成を自動で行う。【解決手段】画像形成装置１０は、メディアセンサー１８が測定した用紙物性に基づいて、記録媒体の種類を判定する第１の判定部１１１と、搬送路１４３を搬送される記録媒体の搬送性能を判定する第２の判定部１１２と、第１の判定部１１１が判定した記録媒体の種類が、製品仕様外の種類である場合に、第２の判定部１１２が判定した搬送性能に基づいて画像形成を行うか否かを決定する画像形成決定部１１３と、を備える。【選択図】図２
