20120008993 | IMAGE FORMATION DEVICE AND IMAGE CORRECTION METHOD - An image formation device comprises imaging units creating toner images in a corresponding color; an intermediate transfer body where the toner images are overlaid in a primary transfer; a secondary transfer unit performing secondary transfers of the overlaid toner images onto a recording sheet; a first misregistration correction unit operable to cause each imaging unit to form a reference pattern, execute a first misalignment reading acquisition process of acquiring a misalignment reading for each pattern, and adjust the imaging units to correct the readings; a storage unit storing the readings; and a second misregistration correction unit operable to cause an imaging unit subset to form reference patterns, execute a second misalignment reading acquisition process of acquiring readings for the subset of patterns and estimating readings in colors for which no pattern is formed from the acquired readings and the stored readings, and adjust the imaging units to correct all readings. | 2012-01-12 |
20120008994 | COLOR IMAGE FORMING APPARATUS - A color image forming apparatus including a test pattern formation portion that forms test patterns of a plurality of colors in an image formation area in which images of the plurality of colors are formed on an image carrier and in an image non-formation area outside the image formation area on the image carrier, a detection portion that detects a shift of each of the test patterns of the plurality of colors formed in the image formation area and a shift of each of the test patterns of the plurality of colors formed in the image non-formation area, a computing portion that obtains, for each color, an offset value indicating an offset between the shift of the test pattern in the image non-formation area and the shift of the test pattern in the image formation area, and a storage portion that stores the offset value for each color. | 2012-01-12 |
20120008995 | IMAGE FORMING APPARATUS - An image forming apparatus includes a first drum; first code forming means for forming a first electrostatic image code outside a developing zone for a toner image; a second drum; second code forming means for forming a second electrostatic image code outside the developing zone for the toner image; a transfer belt provided with an electrostatic image recording track capable of holding the first electrostatic image code transferred from the first drum to the second drum; transferring means for applying a voltage to a side of the transfer belt which is opposite a side contactable to the first drum to transfer the first electrostatic image code onto the electrostatic image recording track; detecting means including an electroconductive member provided which is parallel with the electrostatic image code and which is spaced from a surface of the electrostatic image code of the electrostatic image recording track to be detected with a predetermined gap, and a detecting portion for detecting an induced current generated in the electroconductive member with relative movement relative to the lines of the electrostatic image code, the detecting means detecting the first electrostatic image code of the electrostatic image recording track and the second electrostatic image code of the second drum at a position of the second drum; and control means for controlling image formation on the first drum or the second drum on the basis of a detection result of the detecting means such that the toner image on the second drum is transferred onto a recording material on the transfer belt and overlaid on the toner image transferred onto the recording material from the first drum. | 2012-01-12 |
20120008996 | COLD PRESSURE TRANSFIX IN A SIMPLIFIED PRINTER - A system to combine the transfer and fixing xerographic steps of a xerographic printer into one, as well as to eliminate the need for an electrical field for transfer. The image is transfixed directly from a photoconductor to the paper or other suitable substrate. Appropriate pressure is applied during this step to cold-pressure fix the toner on the paper, taking into account the type of substrate and type of toner. The cold pressure transfix can be done either directly from a photoreceptor, without an intermediate transfer belt (ITB), eliminating all electrostatic transfer subsystems and a fusing operation. Alternatively, for engines with an intermediate transfer belt (ITB), the cold pressure transfix could replace a needed second transfer and fuser system. | 2012-01-12 |
