Abstract
In imaging apparatus (1) a contact heater (9) applies heat and electrical bias to a toner image on an intermediate accumulator (5). The bias is of polarity to repel the toner. The toner image is coalesced such that additional heating may be reduced or eliminated at the transfer to paper (7) by pressure roller (11).
