Abstract: An image-forming apparatus contains a control portion, a thermopile sensor, a temperature sensor, a fan, a heater, a guide plate temperature detection sensor, an external air temperature detection sensor, a fixing temperature detection sensor and the color sensor. The control portion calculates estimated sheet temperature of the conveying sheet using information such as guide plate temperature, external air temperature, fixing temperature and paper weight. The control portion controls the fan or the heater to drive so that sensor temperature of the thermopile sensor approaches the estimated sheet temperature of the sheet. The control portion controls the thermopile sensor to carry out a measurement of the temperature of the sheet when the sensor temperature falls within a set range in relation to the estimated sheet temperature.

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.

Abstract: An image forming apparatus receives setting of an object to be adjusted, on an adjustment object selection screen when selecting an adjustment mode. After the object to be adjusted is set, camera(s) photograph(s) the object to be adjusted so that the image forming apparatus obtains photographed data of current object to be adjusted. Next, the apparatus searches photographed data of the object to be adjusted in the ideal state thereof from the database. Name of the object to be adjusted and related information in the photographed data agree with those of the photographed data of current object to be adjusted. The higher ranked related information is preferentially searched and it is determined whether or not pieces of the higher ranked related information thus preferentially searched agree with each other.
