    摘要： An image forming apparatus includes a movable image bearing member; a transfer device cooperative with the image bearing member to form a nip, through which a transfer material is passed to electrostatically transfer an image from the image bearing member onto the transfer material; where the resistance R range providing proper image transfer is determined in accordance with the equation:-9.16.times.10.sup.3 .times.v+11.68-0.65.ltoreq.log.sub.10 (R.times.L).ltoreq.-9.16.times.10.sup.3 .times.v+11.68+0.65where V (mm/sec) is movement speed of the image bearing member (v.gtoreq.40), R (ohm) is a resistance of the transfer device when a voltage of 3 KV is applied between the image bearing member and the transfer device, and L (mm) is a length of the nip measured in a direction of a generating line of the image bearing member.

    摘要： An image recording apparatus comprises: a printer to form an image onto a recording medium; and a blank forming device to form blanks in the peripheral edge portions of the image formed on the recording medium. The blank forming device sets the blank amount in the front edge portion of the image to be smaller than the blank amount in the back edge portion or sets the blank amount of the image on the scan starting side to be smaller than the blank amount of the image on the scan end side. Even if various tolerances regarding the apparatus, copy transfer paper, conveying apparatus, and the like occur, the image is not deviated out of the paper and the toner image which is not copy transferred onto the photo sensitive drum does not remain and does not make the inside of the apparatus dirty. The effective usable region for image formation can be widened even in the two-sided mode and the multi-mode.

    摘要： An image forming apparatus includes a plurality of devices for forming an image on a rotatable medium and transferring the image onto transfer material. A detector is provided to detect the electrical condition of one of the devices during an initial turn of the rotatable medium prior to image processing. Electrical circuitry then controls the electrical condition of the one device to approach a predetermined value which value is then held for controlling the device during image formation.
