摘要： Paper P has a detection pattern 10a having a length in a main scanning direction M, the length becoming shorter from upstream to downstream along a paper feeding direction F. An image sensor 4 detects the detection pattern and outputs a detection signal including data in the main scanning direction (length y). A control unit 5 calculates a position x of a vertex V of the detection pattern, by using the detection signal, a feeding speed v, an angle ¸ being half of the vertex angle of the pattern, and an imaging time t, so as to correct an image forming position on the back side to coincide with an image on the front side. The detection signal from the sensor with a low operation speed is processed according to a method utilizing a shape feature and the like of the detection pattern, thereby precisely detecting the position of the paper in the feeding direction.

摘要： To add an arbitrary recording medium (Z) as a recording medium that can be used for calibration to maintain the quality of an image to be formed, an image forming unit (120; 130; 140; 150) forms a pattern image on each of a specific recording medium (X) that can be used for the calibration and the arbitrary recording medium (2). A creating unit (301, S1005) creates second conversion setting information (LUTid (Z)) applied to the arbitrary recording medium (Z) to convert luminance information into density information, using first luminance information (I(X)) obtained from the pattern image formed on the specific recording medium (X), second luminance information (I(Z)) obtained from the pattern image formed on the arbitrary recording medium (Z), and first conversion setting information (LUTid (X)) applied to the specific recording medium (X) for converting luminance information into density information. A determining unit (301, S1203) determines a common image formation condition applied to the specific recording medium (X) and the arbitrary recording medium (Z) based on the second conversion setting information (LUTid (Z)).

摘要： Temperature of a printing medium 110 is sufficiently decreased by stopping the printing medium 110 in a discharge path, conveying the printing medium at a low speed, switching a conveyance path, or the like. If the temperature of the printing medium 110 can be sufficiently decreased, the thermochromism phenomenon is suppressed. As a result, it is possible to provide an image forming apparatus capable of achieving highly accurate color matching and color stability.
