The present invention provides a method for manufacturing an identification document that can contain both common information and unique information describing the specific document holder. The information is in the form of indicia applied by digital imaging means. The document itself is in the form of a laminated article having the information affixed to one or more internal layers. Attempt to gain access to these internally imaged layers causes the image to be sufficiently disrupted as to prevent modifying such images.

A developing device including a developer containing magnetic toner grains and includes a main pole for development disposed in a sleeve. Flux density generated by the magnetic pole in a direction normal to the surface of the sleeve outside of the surface has an attenuation ratio of 50% or above. The toner grains have a weight mean grain size of 6.0 μm to 8.0 μm while the toner grains having grain sizes of 5 μm and below occupy 40% to 80% of the entire developer. The toner grains have magnetization strength of 10 emu / g to 25 emu / g in a magnetic field of 5 kOe or magnetization strength of 7 emu / g to 20 emu / g in a magnetic field of 1 kOe. The toner grains reduce toner scattering and image defects despite that they are magnetic, thereby implementing ultrahigh resolution.

A kit and a process for using it to impart wood grain appearances are provided. According to the method, a base coat comprising an opaque, pigmented, water-based paint emulsion is applied to a wood-grain textured substrate and dried. Then, a pigmented, water-based graining coat (most preferably a crosslinkable urethane / acrylic) is applied sparingly, preferably by use of a dampened foam / sponge pad or sprayed, in an amount sufficient to overcoat the base coat and color at least a majority of texture recesses in the substrate and drying. According to the kit aspect of the invention, the kit will comprise: an opaque, pigmented, water-based paint emulsion; a pigmented, water-based graining coat emulsion, optionally packaged in a bottle, such as one with a spray. Optionally, the kit can include an applicator or surface cleaner, a scraper, brush, cloth, sponge, or combination. The process of the invention can be completed within 3 to 12 hours at temperatures ranging from just over 55° F. up to over 85° F., with sufficient time for working both coatings yet without long periods of time where the door or other object is out of service. Timing and ease of application facilitate application by home handyman as well as the professional.

The present invention relates to a water-soluble azo compound or a salt thereof represented by the following formula (1):(wherein, R represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms or a sulfo group, n, m, x and y represent an integer of 1 or 2, 1 to 3, 2 to 4 and 1 to 3, respectively.) and an ink composition containing the same; the above compound or a salt thereof has a hue possessing a high vividness suitable for inkjet recording, provides various fastnesses to recorded matters, and is useful as a yellow coloring matter excellent in storage stability when prepared into an ink composition, and suitable for ink compositions, especially inks for inkjet recording.

An image forming apparatus for calculating a masking coefficient is provides, in which the masking coefficient is calculated by using RGB input image signals obtained by reading a document of which spectral characteristics are known by an image reading part and CMYK output image signals optimal for reproducing a color of the document. The masking coefficient can be also calculated by using difference values between CMYK output image signals obtained from actually read RGB signals and optimal CMYK output image signals.

The present invention relates to an anthrapyridone compound represented by the following formula (1):wherein, n represents an integer number of 1 to 3, R1 represents a hydrogen atom, an alkyl group or the like, R2 represents a hydrogen atom or a methoxy group, R3 represents an anilino group having, as a substituent, at least one group selected from the group consisting of sulfo group, a carboxy group, an alkoxy group, a carbamoyl group, an cyano group, an alkyl group, an anilino group, a phenoxy group, an amino group, a hydroxy group and a mercapto group, an unsubstituted anilino group or the like, or a salt thereof, and provides a magenta coloring matter (compound) having high solubility in water and a hue and vividness which are suitable for inkjet recording and being excellent in fastnesses such as light fastness, moisture fastness and ozone gas fastness on recorded matter; and a magenta ink composition containing it.

An image forming apparatus has a latent image carrier on which a latent image is formed. A developer carrier conveys a one-component non-magnetic developer and develops the latent image either in close proximity to or in contact with the latent image carrier. A voltage application unit applies an AC-superimposed bias voltage to the developer carrier. A regulating member abuts against the developer carrier to regulate the thickness of the developer layer on the developer carrier. The regulating member has a semiconductive member provided at the distal end thereof to produce an electric potential difference between the semiconductive member and the developer carrier, to which the AC-superimposed bias voltage is applied, when regulating the thickness of the developer layer on the developer carrier, thereby forming a line-shaped uneven conveying surface. Thus, the occurrence of banding and longitudinal unevenness and stripes is prevented, and fogging and scattering are also prevented. Further, the occurrence of filming is prevented, thereby allowing formation of a uniform image free from density unevenness.
