摘要： 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.

摘要： 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. F1>F3 and F2>F4 are satisfied, where F1 is a maximum static friction between the transfer roller and the belt member, F2 is a dynamic friction between the transfer roller and the belt member, F3 is a maximum static friction between the shaft of the transfer roller and the bearings, and F4 is a dynamic friction between the shaft of the transfer roller and the bearings.

摘要： 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.

摘要： A first degradation degree detector detects a first degradation degree of one of a plurality of image forming devices for forming toner images, respectively, which is provided at an extreme downstream position in a direction of rotation of an intermediate transfer member. A first degradation degree judgment device judges whether or not the first degradation degree of the extreme downstream image forming device detected by the first degradation degree detector reaches a first level of deterioration. A bias controller decreases a bias to be applied by a transfer device to transfer the toner images, which are formed by the plurality of image forming devices and transferred on the intermediate transfer member, onto a transfer sheet, when the first degradation degree judgment device judges that the first degradation degree of the extreme downstream image forming device detected by the first degradation degree detector reaches the first level.
