Abstract
A toner image carried on a receiving sheet which receiving sheet includes a heat softenable outer layer is fixed or finished by being fed into a nip between a pair of pressure members. The pressure members either embed the toner in the layer or apply a gloss or texture to the heat softenable layer. To eliminate an image defect at the leading edge of the sheet, the pressure between the pressure members is applied by a means having two conditions, one in which said pressure is applied and a second in which it is relaxed. The sheet is sensed as it approaches the nip and the pressure applied just as or after the nip is reached by the leading edge of the sheet.
