Image forming apparatus and colorimetric apparatus

摘要

When a colorimeter is colorimetrically measuring a test pattern, a control unit controls a motor such that the colorimeter and a facing member are closer to each other. A recording material on which the test pattern has been formed is brought into contact with the colorimeter. Even when the colorimeter is not colorimetrically measuring the test pattern, the control unit controls the motor such that the colorimeter and the facing member are closer to each other. The recording material on which the test pattern has been formed is brought into contact with the colorimeter.

主权项

1. An image forming apparatus, comprising:
a fixing unit that fixes a toner image to a recording material; a colorimetric unit that is provided on a conveyance path downstream of the fixing unit in a recording material conveyance direction, and colorimetrically measures a test pattern formed on the recording material; a facing member that is disposed facing the colorimetric unit with the conveyance path interposed therebetween; a drive unit that drives the colorimetric unit or the facing member such that the colorimetric unit and the facing member are closer to each other or separated from each other; and a control unit that controls the drive unit, wherein the colorimetric unit and the facing member are provided on a double-sided conveyance path through which, for image forming on both of a first face and a second face of a recording material, the recording material on which an image has been formed on the first face thereof is conveyed in order to form an image on the second face of the recording material, and in a case where single-sided printing is instructed, the control unit controls the drive unit such that the colorimetric unit and the facing member are closer to each other.
