    Abstract: An image reading apparatus and an image forming system are provided which can reduce the influence of magnification error, detect patches in correct positions, and save the sheets required for adjusting an image. The image reading apparatus makes use of an image scanner which reads patches printed on a sheet P, a spectral colorimeter which colorimetrically measures the patches read by the image scanner, and is provided with a timing compensation unit which compensates the colorimetric measurement timing with which colorimetric operation of the spectral colorimeter is triggered based on the positional information of the patches read by the image scanner, and an image correction unit which corrects the color information of the patches read by the image scanner based on the colorimetric values of the patches colorimetrically measured by the spectral colorimeter.

    Abstract: An image forming apparatus includes the following. A measuring unit measures a physical property of media as a target on which an image is formed. An image forming operator forms an image on the media. A hardware processor controls an operation of the image forming operator and extracts a candidate of a type of media based on a measured result by the measuring unit. An operation receiver receives input to specify one type from the candidate extracted by the hardware processor. The hardware processor controls the image forming operator to form on the media an identification image determined according to a combination of the extracted candidates.

    Abstract: An improved image detection apparatus is described which can colorimetrically measure an appropriate number of patches while inhibiting unnecessary sheet discharging. A correction chart consists of a plurality of patches linearly arranged in the form of a plurality of patch arrays which are parallelly arranged in the sheet width direction. The image detection apparatus includes a paper conveying unit for conveying a sheet on which the correction chart is formed, an image reading unit and a colorimetric unit which outputs the color information of each patch by performing the colorimetric process with the patch array consisting of a line of the patche. Then, while circulating a sheet, a control unit performs switch control for switching the patch array from one to the next to be colorimetrically measured by the colorimetric unit.
