摘要： An image forming apparatus has an image forming unit for forming an image on a recording medium; a conveying unit having a conveying part for conveying the recording medium while contacting the recording medium; a detection unit for detecting the chromaticity or the density of the image formed on the recording medium; and a control unit for controlling the image forming unit based on the chromaticity or the density of the image detected by the detection unit. The image forming unit forms an image for which the chromaticity or the density is to be detected at a predetermined position on the recording medium whereat the recording medium does not contact the conveying parts of the conveying unit. With this configuration, an image having a stable quality can be formed.

摘要： An image of stabilized tint is output even if a supplied transfer medium is changed to a transfer medium of a different surface gloss or type of paper. If the supplied transfer medium has changed, the tint of a corrective image formed on the transfer medium is sensed, a tint correction of an image forming portion is performed based upon result of sensing, and corrective data of the tint correction and information relating to the transfer medium is stored. If a change of the transfer medium is sensed subsequently, a determination is made as to whether the transfer medium is substantially the same transfer medium, based upon the stored information relating to the transfer medium. If the transfer medium is substantially the same, then image processing is executed based upon the stored corrective data.

摘要： An image of stabilized tint is output even if a supplied transfer medium is changed to a transfer medium of a different surface gloss or type of paper. If the supplied transfer medium has changed, the tint of a corrective image formed on the transfer medium is sensed, a tint correction of image forming means is performed based upon result of sensing, and corrective data of the tint correction and information relating to the transfer medium is stored (S209 to S217). If a change of the transfer medium is sensed subsequently (“NO” at S204), whether the transfer medium is substantially the same transfer medium is determined based upon the stored information relating to the transfer medium (S214). If the transfer medium is substantially the same, then image processing is executed based upon the stored corrective data (S216, S205 to S207).
