Description

上記目的を達成するため、シートに測定用画像を形成する像形成手段と、測定対象に光を照射し、当該測定対象からの反射光の各波長における光量を測定する測定手段と、シートを給紙して前記像形成手段により当該シート上に測定用画像を形成させ、当該シート上の測定用画像を前記測定手段により測定させる第１のモードと、既に測定用画像が形成されたシートを給紙し、前記像形成手段による画像形成を経ずに当該シート上の測定用画像を前記測定手段に測定させる第２のモードのいずれかを選択する選択手段と、前記選択手段により選択されたモードにしたがって、前記測定手段に測定用画像の測定を行わせる制御手段と、を有し、前記選択手段が前記第１のモードを選択した場合に前記シートが搬送される第１搬送経路と、前記選択手段が前記第２のモードを選択した場合に前記シートが搬送される第２搬送経路とは異なることを特徴とする。 In order to achieve the above object, an image forming means for forming a measurement image on the sheet, a measuring means for irradiating the measurement object with light, and measuring a light amount at each wavelength of reflected light from the measurement object, and a sheet are provided. A first mode in which a measurement image is formed on the sheet by the image forming unit and the measurement image on the sheet is measured by the measurement unit, and a sheet on which the measurement image has already been formed are fed. A selection unit that selects one of the second modes in which the measurement unit measures the measurement image on the sheet without paper formation and image formation by the image formation unit; and the mode selected by the selection unit according, wherein possess control means for the measuring means to perform the measurement of the measurement image, and a first conveyance path for the sheet is conveyed when said selecting means selects said first mode, said Selection Means are different from each other and the second transport path in which the sheet is conveyed when you select the second mode.
