In a corresponding manner, the embodiment shown in Figure 2

exposure station 20 in Figure 1. Finally, the excess toner is
removed at the decorating station that has not been fixed to the

rotating brush 300. All of this is discussed at page 7 of Doyle.
Furthermore, the Example 4 discussion at the bottom of page
8 of Doyle also indicates the removal of non-fixed toner
particles by the use of a separate plastic film placed upon the
