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.
