Abstract
A small particle toner image is formed on a primary image member, such as a photoconductor, and electrostatically transferred to an intermediate image member and then electrostatically transferred to a receiving sheet. The intermediate image member is chosen to have characteristics making the toner less attractive to the primary image member, but more attractive to the receiving sheet, than the intermediate. The intermediate transfer member can include a base of a relatively compliant material having a Young's modulus 10.sup.7 Newtons per square meter or less with a very thin outer skin of a harder material having a Young's modulus of 5.times.10.sup.7 Newtons per square meter or more.
