20140153945 | IMAGE FORMING APPARATUS - An image forming apparatus includes plural image carriers, an intermediate transfer body, a contact and separation mechanism, a selection member, plural first transfer units, a second transfer unit, and an adjustment member. Each image carrier carries a toner image. The intermediate transfer body is disposed so as to be in contact with one or more image carriers. The contact and separation mechanism causes the intermediate transfer body to be in contact with or separated from the image carriers. The selection member selects a first contact state or a second contact state. Each first transfer unit forms a transfer electric field in a first transfer region to transfer a toner image onto the intermediate transfer body. The second transfer unit forms a transfer electric field in a second transfer region to transfer toner images onto a recording material. The adjustment member adjusts first transfer conditions. | 06-05-2014 |
