The image processing method includes: generating profiles for color reproduction, classified for each of recording papers, from at least one of particular characteristic data of the each recording paper, which is generated on the basis of factors that affect color reproduction and particular generation information of the each recording paper, which is obtained by printing plural patch patterns at the recording paper and performing colorimetry of the printed patch patterns; and when implementing basic extraction control for extracting a profile that matches in at least one of the characteristic data and the generation information, if no profile that matches in at least one of the characteristic data and the generation information is extracted, extracting a profile that approximates in accordance with a pre-specified order of priority determination procedure to be a candidate.

Image processing method and image forming device for generating profiles for color reproduction

Information indicating an area of an image and information indicating attributes of the image have been stored in an IC chip attached to an original paper. When a copying apparatus performs a character recognition process operation with respect to an image displayed on the original paper, the copying apparatus reads the information related to the area of the image and the information related to the attribute of this area from the IC chip attached to this original paper. Then the copying apparatus separates an area where a character is displayed therefrom. The copying apparatus executes the character recognition process operation with respect to the image of the separated area.

Image processing method and image processing computer program

A toner for developing an electrostatic image, the toner having a core-shell structure, wherein the toner comprises: a colorant; a binder resin; and a filler, and wherein the toner has a flow tester &#xbd; effluent temperature of from 60 to 100&#xb0; C., and a shell of the toner comprises a thermoplastic resin.

Toner for developing electrostatic image, method for producing the same, developer for developing electrostatic image, and image forming method

A toner for developing an electrostatic charge image, includes: a binder resin formed by reacting a polymerizable aromatic monomer having an ethylenically unsaturated double bond conjugated to an aromatic ring thereof, a nitrogen-containing polymerizable aliphatic monomer having an ethylenically unsaturated double bond and a sulfur-containing aliphatic compound to each other; and a colorant, wherein a ratio (MN/MS) of an amount of nitrogen (MN) to an amount of sulfur (MS) is in a range of from 1.0 to 15.

Toner for developing electrostatic charge image, electrostatic charge image developer, image forming method and image forming apparatus

A cleaner-less image forming method includes forming an electrostatic latent image on a electrostatic latent image carrying member; developing the electrostatic latent image with a developer comprising a toner and a carrier to form a toner image; and transferring the toner image. The carrier has a median of an arithmetic average height distribution of from 0.45 to 0.65 &#x3bc;m, and the toner includes an external additive and has an average circularity of 0.975 or more.

Image forming method

An UI section receives a printing parameter set by a user. A data reading section reads a printing parameter from an original paper. An image reading section reads an image from the original paper. When an IC chip has been attached to the original paper, a parameter selecting section selects a printing parameter thereof, whereas in other cases, the parameter selecting section selects a printing parameter, which is set by the user. An image processing section and a printing control section execute an image processing operation and a printing operation in accordance with the selected printing parameter.

Image forming system and image forming method

When two or more sheets of images, which have been read from two or more sheets of originals are printed on a single sheet of first printing paper, original information related to the originals is stored into an IC chip attached to the first printing paper. Thereafter, when a user desires to reproduce the originals by using this first printing paper, the original information stored in the IC chip is read therefrom. Based on the read original information, the images read from the originals are printed respectively in the same sizes as those of the respective originals.

Image forming apparatus and image forming method

An image output control apparatus is capable of outputting normal images and stereo images from an output unit to a display device or a printer so that the normal images and the stereo images may be distinguishable. The image output control apparatus includes an image type determining unit that determines whether an image to be output is a stereo image or a normal image, the stereo image being composed of a pair of a left-eye image and a right-eye image, and an output form control unit that controls an image output form to distinguish a first image output form from a second image output form, the first image output form being used for outputting the stereo image, and the second image output form being used for outputting the normal image, according to the determination of the image type determining unit.

Image output control apparatus, image output control method, image output control program and printer

An image having no secrecy is printed on a non-secret information display area of an original paper, whereas an image having secrecy, which should be originally printed, is not printed on a secret image display area. When the original paper is copied on a printing paper, an image read from the original paper is printed on a secret image display area, whereas a secret image is printed on a non-secret information display area only when an access operation to the secret image is authenticated.

An UI section accepts operation of a user. A setting selection section judges as to whether this user operation instructs a process operation executed in accordance with setting information of an IC chip attached to an original document, or another process operation executed in accordance with setting information entered by the user. In the former case, an operation control section controls a data reading section so as to read out the setting information from the IC chip attached to the original document, and also, controls a print control section to perform printing/FAX transforming operations in accordance with this read setting information. In the latter case, an operation control section controls a data writing section in order to write the setting information entered by the user into the IC chip.

A copying apparatus detects as to whether or not an IC chip is present in an original paper. When the IC chip is detected, the copying apparatus reads data from this IC chip. When the read data is additional information, which can be printed as an image, the copying apparatus stops a printing process, and notifies a message indicating that the read data is the additional information to the user and then, waits for an instruction issued by the user. When the user instructs to print the additional information, the copying apparatus prints the image read from the original paper and the additional information read from the IC chip on a printing paper in an output format designated by the user.
