Abstract: An image forming apparatus has: a recording head for forming an image on a recording medium; a color correction processing device which performs a color correction processing with respect to an input image data; an image output controller which controls the recording head according to the image data after performing the color correction processing in such a manner that the image corresponding to the image data is formed on the recording medium; a patch forming controller which controls the recording head so as to form a patch for colorimetry on the recording medium; a memory device for storing an output condition for forming the image, and measured results of the patch for colorimetry formed under the output condition; and a correction data change device which changes a correction data used for the color correction processing performed by the color correction processing device, when difference between the measured results of the patch for colorimetry that are obtained by forming the patch for colorimetry and

Abstract: An antireflective film comprising a transparent substrate and a low refractive index layer formed by coating a low refractive index layer-forming composition, wherein the low refractive index layer-forming composition contains at least one of a hydrolysate of an organosilyl compound represented by the following formula (1) and a partial condensation product of the hydrolysate, and an outermost face of the antireflective film has a centerline surface roughness Ra of from 0.005 to 0.20 ?m: R11mSi(X11)n??(1) wherein X11 represents —OH, a halogen atom, —OR12 or —OCOR12 in which R12 represents an alkyl group; R11 represents an alkyl group, an alkenyl group or an aryl group; and m and n are each a positive integer provided that m+n is 4.

Abstract: The state of a photosensitive material processing solution is easily determined from values of multi-dimensional analysis by utilizing Mahalanobis distance. The Mahalanobis distance is calculated, and a determination is made as to whether or not the Mahalanobis distance is greater than or equal to a threshold value. If the Mahalanobis distance is less than the threshold value, the processing solution is determined to be normal, the Mahalanobis distance is displayed on a display unit, and a determination is made as to whether or not the number of sets m of normal values has become greater than or equal to a predetermined value m.sub.0. If m.gtoreq.m.sub.0, data of the characteristic values in the oldest set in a time series is deleted, and a set of data of newly detected characteristic values is added to calculate the Mahalanobis distance and update a database.
