摘要： Color toner images are transferred in registry to a receiving sheet held on a transfer drum. To facilitate releasing the sheet with the last image the drum surface is roughened, providing at least 0.002 inches between peaks and valleys. To offset difficulties created by such roughening in initial securing of the sheet to the drum, a transfer field is not applied as the leading edge of the sheet leaves the nip. The transfer field is applied after a short portion of the sheet, for example, 0.25 inches has left the nip.

摘要： An electrostatographic copier or printer includes a transfer apparatus which transfers two or more images to the same surface in registration, for example, to form a multicolor image. The copier or printer forms large size electrostatic images on a moving image member with the long dimension of the images parallel to the direction of motion and small size images with their long dimension across the direction of motion. A transfer drum with a circumference substantially equal to the distance between comparable points on the image member between consecutive large images or pairs of small images transfers consecutive large images or pairs of small images in registration.The preferred transfer drum is of the type which rotates secured copy sheets into transfer relation with two or more toner images to receive them in registration. The drum includes means for either securing one large copy sheet or two smaller copy sheets. This doubles the speed of the copier or printer when in the smaller sheet mode.
