US 2013/0094041 A1 · IMAGE FORMING APPARATUS

Abstract

An image forming apparatus includes an image forming unit configured to form a measurement image on a recording paper by using a color material, a fixing unit configured to fix a plurality of measurement images onto the recording paper by heating the measurement images, a measurement unit configured to measure the measurement images fixed onto the recording paper downstream of the fixing unit in a conveyance direction of the recording paper, a cooling unit configured to cool the recording paper heated by the fixing unit, and a control unit configured to perform control such that a cooling capacity of the cooling unit in a case where the measurement unit measures color of the measurement images is higher than a cooling capacity of the cooling unit in a case where the measurement unit measures density of the measurement images.

An image forming apparatus comprising:

an image forming unit configured to form a measurement image on a recording paper by using a color material;
a fixing unit configured to fix a plurality of measurement images onto the recording paper by heating the recording paper;
a measurement unit configured to measure the measurement images fixed on the recording paper downstream of the fixing unit in a conveyance direction of the recording paper;
a cooling unit configured to cool the recording paper heated by the fixing unit;
and
a control unit configured to control the cooling unit such that it removes more heat energy from the measurement image when measuring color of the measurement image than when measuring density of the measurement image.
