20080226313 | Image forming apparatus and image forming method - An image forming apparatus includes an image carrier, an intermediate transferring body and a contact type secondary transferring member transferring an image from the intermediate transferring body to a recording medium. The apparatus forms an image with respective developers for multiple colors and uses a predefined adjustment pattern to make density adjustment and position adjustment of respective color images. After execution of the density adjustment and/or the position adjustment, a stain prevention pattern is formed with a yellow developer to cover an area where the adjustment pattern is attached to the secondary transferring member. | 09-18-2008 |
20090060540 | IMAGE FORMING DEVICE - An intermediate transfer tandem type image forming device which has multiple first stage transfer units set parallel and a single power unit which simultaneously applies bias to the multiple first stage transfer units. When executing successive printing or both-sides printing and there is a need to change the bias value of the first stage transfer bias due to a mix of multiple types of recording media, the device is able to hold down electricity consumption, sustain image quality, and form images productively. When executing successive printing or both-sides printing, the application timing of the changed transfer bias due to the detection of a different recording medium to that of the initial medium is placed after the previous first stage transfer of a final color toner image is completed. | 03-05-2009 |

20100239334 | Image forming apparatus - An image forming apparatus includes an image carrier; a movable endless belt member forming a nip between the image carrier; and a transfer roller made of metal contacting the belt member at a region corresponding to the nip. At the nip, a toner image on the image carrier is transferred onto the belt member. The transfer roller slidably rotates in bearings supporting its shaft. Members having a higher friction coefficient than that of the transfer roller are provided at end portions of the transfer roller. F | 09-23-2010 |

20110273572 | IMAGING APPARATUS - An imaging apparatus includes a correction lens configured to correct a shake of a subject image formed on an imaging device, a driver configured to drive the correction lens, a detector configured to detect an amount of shake of the imaging apparatus, a determining unit configured to determine, based on an amplitude of an output from the detector, whether or not the shake of the imaging apparatus is within a normal range of camera shake, and a controller configured to control the driver based on a result of determination made by the determining unit. The controller controls the driver so as to drive the correction lens in a first mode when it is determined that the shake of the imaging apparatus is within the normal range of camera shake, the first mode being such that the correction lens is driven according to a result of detection by the detector, and so as to stop the correction lens or to drive the correction lens in a second mode when it is determined that the shake of the imaging apparatus is out of the normal range of camera shake, the second mode being such that an amount of movement of the correction lens is suppressed more than that for the first mode. | 11-10-2011 |
20120320227 | IMAGING APPARATUS - An imaging apparatus includes an optical system, an imaging device that captures an image imaged via the optical system to generate image data, a detecting unit that detects a shake of the imaging apparatus in a rotating direction, a cutting-out unit that cuts out data in a predetermined cutting-out region in a region of the image data generated by the imaging device, and a recording unit that records the cut image data in a recording medium. The cutting-out unit determines a rotating center position according to a predetermined condition (for example, the focal length of the optical system or move amount of the imaging apparatus), rotates the cutting-out region around the rotating center position to reduce an effect of the shake in the rotating direction detected by the detecting unit on the image imaged on the imaging device, and cuts out the image data from the rotated cutting-out region. | 12-20-2012 |
