A color image forming apparatus of a so-called tandem type which has image forming units in correspondence with colors is provided. In the color image forming apparatus, a color discrepancy amount storage unit stores information of a color discrepancy amount of each of the image forming units, which is measured in advance. A first color discrepancy correcting unit performs color discrepancy correction in a pixel unit by performing coordinate conversion of bitmap data to be printed based on the information of the color discrepancy amount stored in the color discrepancy amount storage unit. A second color discrepancy correcting unit performs color discrepancy correction in less than a pixel unit by performing tone correction of the bitmap data corrected by the first color discrepancy correcting unit based on the information of the color discrepancy amount stored in the color discrepancy amount storage unit.

An electronically updatable display having an electronically updatable display media with two or more color sets is disclosed, wherein the viewed color sets, and the image, are changeable.

Provided is a white light emitting organic electroluminescent device, which includes a transparent substrate, a first element, and a second element, wherein the first element includes a first anode, a first element organic layer, and a reflective cathode sequentially disposed on a first substrate of the transparent substrate, and wherein the second element includes a second anode, a second element organic layer, and a transparent or translucent cathode sequentially disposed on a second surface of the transparent substrate.

A main object of the present invention is to provide a high-quality color filter having a colored layer formed by use of a difference in wettability in the surface of a photocatalyst containing layer, wherein white spots and color unevenness are not present in the colored layer and a method for producing the same. To achieve the object, the present invention provides a color filter comprising: a base material; a light shielding part formed on the base material and containing a light shielding material and a resin; a photocatalyst containing layer formed to cover the base material and the light shielding part and containing a photocatalyst and an organopolysiloxane; and a colored layer formed on the photocatalyst containing layer in an opening part made in the light shielding part, wherein the widths of thin film regions of both sides each having a film thickness decreased in a tapered form from a central portion of the light shielding part are each in the range from 20 to 40% of the line width of the light shielding part, and the film thickness of the photocatalyst containing layer is in the range from 0.01 to 0.5 μm.

An image detector has an I / V converter for converting, into a voltage output., a current output as a result of a photoelectric element arranged in a traveling direction of an intermediate transfer belt having received light reflected from the intermediate transfer belt and light reflected from toner images formed on the intermediate transfer belt; a peak-hold unit for holding an output voltage into which the light reflected from the intermediate transfer belt has been converted by the I / V converter; and a computation unit for detecting a difference between the output voltage of the peak-hold unit and an output voltage into which the light reflected from the toner images of respective colors has been converted by the I / V converter.

An apparatus for coloring landscape material, including a frame and a drum rotatably mounted on the frame. The drum includes a longitudinal centerline and a wall that defines a chamber. A plurality of projections are formed on an inner surface of the wall in the chamber. A colorant delivery system includes a dispensing structure extending into the chamber and defines outlets for emitting colorant. The outlets are generally offset from the drum longitudinal centerline. The colorant delivery system delivers colorant to the chamber, and the landscape material is tumbled in the chamber by the projections when the drum rotates. A method for coloring landscape material is also provided.

A light emitting device includes a light emitting element having an emission peak wavelength in a range of 380 nm to 420 nm and a fluorescent member including at least one fluorescent material that is excited by light from the light emitting element for light emission, wherein a mixture of light from the light emitting element and light from the fluorescent material has a correlated color temperature in a range of 2000 K to 7500 K as measured according to JIS Z8725, and the light emitting device has a spectral distribution in which, when the integral value over a wavelength range of 380 nm to 780 nm is normalized to 100%, the proportion of an integral value over a wavelength range of 380 nm to 420 nm is 15% or more, and the ratio a as defined by the expression (1) is 0.9 or more and 1.6 or less.
