Abstract: When at least one of first image data and second image data is captured, according to a moving speed of an object while an image sensor is capturing an image, exposure time for capturing the image is controlled to decrease a difference between object blur widths in a direction in which the object moves.

Abstract: A belt pressurizing device includes: an endless belt that is circularly driven; a pressing member that presses the endless belt against a facing member with the endless belt interposed between the pressing member and the facing member; and a lubricant supplying member that supplies lubricant to reduce sliding resistance of the endless belt pressed by the pressing member, so as not to be in contact with the endless belt.

Abstract: In a color misalignment detection method, an alignment pattern is obtained by designating a plurality of lines having line width and line intervals formed by superposing a line image of a black color as a reference color and a line image of a color other than the reference color, for example, a cyan line image, as one patch, and continuously forming these patches by shifting the relative position between the line images of the two colors by an optional quantity. An alignment pattern detection sensor has a light emitting diode and a photodiode. These elements are arranged along the scanning direction of the alignment pattern such that the photodiode can only receive diffused reflected light of reflected light from the alignment pattern. A spot shape of the light emitting diode and a spot shape of the photodiode are both formed in a square shape.

Abstract: A developing device develops an electrostatic latent image on an image bearing body, and includes first, second and third rollers, a developing belt and a developer supply member. The developing belt, which is entrained about the first, second and third rollers, is opposed to the image bearing body between the first and second rollers, and is in contact with the developer supply member between the first and third rollers. The developer supply member supplies a developer to the developing belt.

Abstract: In a beltless tandem-type image forming apparatus, a plurality of pairs of transfer rollers are placed side by side at intervals along a conveying direction of sheets. A control section independently conveys sheets in sequence through nip sections of respective pairs of transfer rollers driven by a driving section while sequentially transferring images formed by an imaging section onto the sheets. Conveying speeds of the respective pairs of transfer rollers controlled by the driving section are gradually decreased for every pair of transfer rollers from an upstream side toward a downstream side along a conveying direction of the sheets, and consequently, a driving period for driving the respective pairs of transfer rollers to convey each sheet is gradually increased for every pair of transfer rollers from the upstream side toward the downstream side along the conveying direction of the sheets.

Abstract: Exemplary embodiments provide a direct imaging system and methods for direct marking an image using the system. The disclosed direct imaging system can eliminate the creation of a latent image and can be used in an electrophotographic machine and related processes. Specifically, the direct imaging system can include a direct marking substrate (e.g., a printing substrate) and a development belt member closely spaced from the direct marking substrate. In one embodiment, the development belt member can include a plurality of actuator cells with each actuator cell controllably addressable to eject one or more toner particles adhered thereto. The ejected toner particles can transit the space between the donor belt member and the direct marking substrate, and directly marking onto the direct marking substrate forming an image.

Abstract: An image forming apparatus having therein an image carrier, an intermediate transfer belt is trained about plural rollers and is located at a position where it comes in contact with the image carrier, a primary transfer roller that is arranged to face the image carrier through the intermediate belt for the purpose of transferring toner on the image carrier onto the intermediate transfer belt, wherein the following expression holds when Ft (kgf) represents tension of the intermediate transfer belt, Fr (kgf) represents pressing force of primary transfer roller and d (mm) represents a shift amount for the image carrier and the primary transfer roller, Fr?(0.05×Ft+0.11)×d?0.3.

Abstract: A process for adjusting a web tension in a web-fed rotary printing machine addresses the problems of processing variables which are not precisely quatifiable, while minimizing the influence of the press operator. This is achieved by adjusting the web tension using rules of fuzzy logic.

Abstract: A magnetic brush development station for developing latent image charge patterns supported on a moving image support member of an electrostatographic reproduction apparatus. The magnetic brush development station includes a housing located in operative association with an extended run of the image support member. The housing has a portion constituting a sump for developer material, and a portion defining an opening facing the image support member. Further, the magnetic brush development station includes an applicator for applying developer material to a latent image charge pattern on the image support member to develop such latent image charge pattern. The applicator includes a sleeve located in the last mentioned portion of the housing, above the developer material sump, the sleeve having a development surface operatively associated with the image support member through the opening and configured to complementarily conform to the run of the image support member to define an extended uniform development zone.

Abstract: A development system is which includes a flexible belt having a magnetic surface. The belt has a static magnetic field pattern for transporting developer material to a development zone; and a magnetic system for generating a superimposed alternating magnetic field to agitate developer material in the development zone in order to produce a charged toner cloud intended for the non-interactive development of latent electrostatic images.
