Abstract:
A developing device includes a first developing roller, a second developing roller, a first end portion configured to restrict the amount of developer on the second developing roller, a restriction member, and a collecting roller configured to collect developer on the first developing roller. The second end portion is located at a position where magnetic force interference with a magnetic force generated by the second developing roller and the collecting roller is not caused.
Abstract:
An image forming apparatus includes: a determination section configured to determine whether there is a possibility of generation of an image defect during a printing job for image formation on a plurality of pages based on image data included in the printing job; and a changing section configured to change an order of the pages to be subjected to image formation such that an image defect is not generated when the determination section determines that there is a possibility of generation of the image defect.
Abstract:
An image forming apparatus uses a first developer conveyance amount and a first correction amount calculated respectively in a first state, a second developer conveyance amount and a second correction amount calculated respectively in a second state in which the developer conveyance amount is smaller than the developer conveyance amount of the first state, and a third developer conveyance amount detected in a third state in which the developer conveyance amount is smaller than the developer conveyance amount of the first state and is larger than the developer conveyance amount of the second state to calculate a third correction amount for correcting density unevenness of the toner image in the third state, and perform control to correct the density unevenness of the toner image based on the calculated third correction amount.
Abstract:
A method of controlling an image forming apparatus, an image forming apparatus and image forming system are described, with which banner paper can be processed by appropriately detecting the banner paper in the fixing position when the conveyance of the banner paper is halted. The image forming apparatus comprises a paper conveying unit for conveying banner paper, an image forming unit for transferring an image to the banner paper, a fixing unit for fixing the image to the banner paper in a fixing nip by heating and pressing the banner paper conveyed along a conveying route, and a control unit. This control unit identifies information about the paper position which coincides with the fixing nip when the conveyance of the banner paper is halted and information about the amount of paper deformation of the banner paper in the paper position, and outputs the information which is identified.
Abstract:
An extraction apparatus is a sample removal apparatus that removes a sample collected from a living body. The extraction apparatus includes: a storage container holder that holds a storage container of a sample and is capable of being placed at a sample receiving section where the sample is supplied to the storage container, and a removal section that causes the sample to be discharged from the storage container to a predetermined place; a housing that covers the storage container holder and the removal section; and a supply section that allows for supply of the sample from the outside of the housing to the storage container in the housing.
Abstract:
A detection device includes a support base having a rotation surface rotatable in a plane, a detector provided on the rotation surface and displaced with rotation of the rotation surface, a first supply port and a second supply port provided above the rotation surface, and an optical measurer measuring optical characteristics of a first supply material and a second supply material supplied from the first supply port and the second supply port to the detector.
Abstract:
An image forming apparatus includes a plurality of image formers each capable of forming, on a sheet, an overlap image and a non-overlap image, a fixer that fixes, on the sheet, a whole image composed of the overlap images and the non-overlap images, and a hardware processor that controls each of the plurality of image formers such that a difference in image at a boundary between the overlap image and the non-overlap image is reduced in the whole image.
Abstract:
An image forming apparatus includes: an image forming unit including a rotating member; a rotation position detecting unit that detects a rotation position of the rotating member; an image density detecting unit that detects density of an image; an image information analysis unit that analyzes image information; a density profile management unit that manages a density profile; a correction data generation unit that generates correction data; a density correction unit that performs density correction; and a density correction control unit that sets a density correction level, wherein when the density correction level is set at reference accuracy, the density correction unit corrects density, and when the density correction level is set at accuracy higher than the reference accuracy, the density profile management unit forms a corrective patch image and generates a new density profile, the correction data generation unit updates the correction data, and the density correction unit corrects density.
Abstract:
An image forming apparatus includes: a conveyance section configured to convey a sheet in a direction opposite to a first conveyance direction during image formation, the direction being a second conveyance direction; and a distortion correction section disposed on an upstream side of a transfer nip in the first conveyance direction and configured to correct, when the sheet is conveyed by the conveyance section in the second conveyance direction, distortion of the sheet generated when the sheet passes through a fixing nip.
Abstract:
A developing device includes a developing roller which includes: a magnet roller having a plurality of magnetic poles in a circumferential direction; and a developing sleeve rotatably supported along an outer peripheral surface of the magnet roller, and which is configured to supply a toner to an image bearing member. The magnet roller is configured so that the relative position thereof to the developing sleeve is changeable.
