摘要:
An image formation system for forming a plurality of images different in color on a transfer material supported on an endless support rotated or directly on the endless support, thereby forming an image, and for forming color shift detection patterns on the endless support rotated, sampling the color shift detection patterns, and performing predetermined control operation, characterized in that color shift detection patterns for detecting cyclic rotation change occurring in the image formation system are provided.

Specific pattern images are transferred from respective photoreceptors onto the circumferential surface of a transfer belt. By detecting the specific pattern images with sensors, misregistration amounts on a transfer belt are calculated by a misregistration correction control section. Averages of the misregistration amounts for respective colors are calculated for each region that corresponds to a single recording medium placed on the transfer belt. The scanning timings of image writing units are controlled by an image signal output control section based on the calculated averages. As a result, toner images formed on the respective photoreceptors are transferred to proper positions of any recording medium being placed on the transfer belt.

An image formation device is provided with a discharge tray configured to receive the sheet discharged from a discharge exit, a guide portion configuring at least a part of a first feed path and a second feed path extending from a fixing unit to the discharge exit, a reversibly rotatable roller configured to reverse a feeding direction of the sheet fed from the fixing unit to the discharge exit so that the sheet is reversely fed toward an entrance of the of the developing unit. In this configuration, the first path and the second path are converged to form a converged feed path on the discharge exit side, the reversibly rotatable roller is provided in the converged feed path, and a converged feed path guide portion, which is a part of the guide portion, is displaceable to a position to expose the converged feed path to outside.

A method of readily forming a dye-sensitized solar cell having a porous layer of increased thickness. The dye-sensitized solar cell includes a translucent substrate, and a plurality of collecting electrode traces formed on the translucent substrate. The solar cell also includes a trench that is trapezoidal in cross-section and is formed on the translucent substrate between the collecting electrode traces. The solar cell also includes a porous layer upon which a sensitizing dye is adsorbed. The porous layer covers the translucent substrate within the trench and the collecting electrode traces.

An image-forming apparatus includes: a process cartridge including a photosensitive drum having a photosensitive surface and a rotational axis; an exposing unit having a first end, a second end opposing the first end, and an exposing surface formed on the first end and oriented in a predetermined direction; and a supporting member on which the process cartridge is mountable from a side of the second end. The supporting member has a pivotal supporting portion configured to pivotably movably support the process cartridge between an exposing position where the photosensitive surface of the photosensitive drum faces the exposing surface and a retracted position where the photosensitive surface of the photosensitive drum is offset from the exposing surface, the exposing surface being configured to expose the photosensitive surface of the photosensitive drum to form an electrostatic latent image when the process cartridge is positioned at the exposing position.

An image forming apparatus, including: an electrophotographic image forming unit which forms an image on a recording medium; a fixing unit which thermally fixes the image; an insulating chute disposed between the image forming unit and the fixing unit, including: a guide face and a back face, and configured to guide the image-formed recording medium to the fixing unit; and a planar metal member disposed on the back face and expanding to a first end edge portion as an edge portion of one of end portions of the chute nearer to the fixing unit. The metal member includes a second end edge portion that is an edge portion of one of end portions of the metal member nearer to the fixing unit. The second end edge portion has an acute angle in cross section as viewed in a widthwise direction of the recording medium.

An image forming apparatus includes a belt, a cleaning member, a backup member, a pressing-force changing mechanism, and a control unit. The cleaning member is disposed in confrontation with the belt. The backup member is disposed to pinch the belt in cooperation with the cleaning member. The pressing-force changing mechanism is configured to change a pressing force acting between the cleaning member and the belt in a state in which the cleaning member is in contact with the belt. The control unit controls the pressing-force changing mechanism to change the pressing force.

An image-forming device includes a photosensitive drum, a conveying unit, a transferring roller, an optical sensor, a ground connector. The photosensitive drum carries a developer image. The conveying unit includes a driving roller, and an endless belt. The endless belt is disposed in confrontation with the photosensitive drum and transferring roller. The optical sensor is disposed near the driving roller and detects the developer image on the endless belt. The first connection member has a first electrical resistance and is connected between the driving roller and a ground connector electrically grounded. The second connection member has a second electrical resistance and is connected between the endless belt and ground connector. The first electrical resistance is less than the second electrical resistance so that an electrical charge is quickly removed from the driving roller and more gradually removed from the endless belt, thereby simultaneously preventing adverse effects on image formation and adverse effects on the optical sensor disposed near the driving roller.
