The image-forming-condition determination unit forms an image pattern, acquires periodical density variation information sensed by the density sensor and detection information of the rotation-position detector, and determines an image forming condition based on the periodical density variation information and the detection information acquired. The image carrier and the transfer body are different in linear velocity in an image formation in which the toner image is transferred to a recording medium. The image carrier and the transfer body are controlled to be equal in linear velocity in an information acquisition in which the image-forming-condition determination unit acquires the periodical density variation information and the detection information. | 09-18-2014 |
20140270828 | IMAGE FORMING APPARATUS - An image forming apparatus includes a latent-image bearing body, a charging unit, a latent-image writing unit, a development unit, a development power, and a bias control unit. After a start of an image forming operation, the bias control unit performs a process of constantly maintaining an output of a development bias at an adjustment bias value. The adjustment bias value is a central value in a periodic fluctuation range of the output of the development bias. At a timing at which a difference of the development bias from the adjustment bias value in the periodic fluctuation range is less than or equal to a predetermined threshold value, the bias control unit performs switching from the process of constantly maintaining the output of the development bias at the adjustment bias value to a process of periodically changing the output of the development bias based on development bias control data. | 09-18-2014 |
20150316885 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus includes a controller to perform a primary image forming condition determination control to determine a primary image forming condition for each of a plurality of image forming devices in a multi-color image forming mode based on a toner adhesion amount adhered to a transferred image bearer that is detected by a toner adhesion detector and a secondary image forming condition determination control to determine a secondary image forming condition for a particular at least one of the plurality of image forming devices in a particular color image forming mode based on the toner adhesion amount. The controller performs the primary image forming condition determination control at a predetermined time and determines whether or not to perform the secondary image forming condition determination control based on the toner adhesion amount detected under the primary image forming condition determination control. | 11-05-2015 |
20150362868 | IMAGE FORMING APPARATUS - An image forming apparatus includes an endless belt-shaped image bearer that is rotatably supported and entrained around rollers; a transfer member positioned to contact an outer surface of the image bearer; a transfer device to transfer a toner image conveyed while being carried on the outer surface of the image bearer onto a transfer medium conveyed between the image bearer and the transfer member; a toner image sensor to detect the toner image transferred onto the transfer medium; and a conveyance speed controller to fine-tune a conveyance speed of the transfer medium. Based on fine-tuning data of the conveyance speed controller, a detection result of the toner image sensor is corrected and image forming conditions are corrected based on the corrected detection result. | 12-17-2015 |
