Claim 15:
16. A printing device comprising:
a main marking station comprising:
a cylindrical transfer member comprising:
a rigid cylindrical core member,
an intermediate layer, formed from a dielectric material, bonded to the core member, and
an outer layer bonded to the intermediate layer, the outer layer defining an outer surface of the transfer member;

a plurality of color stations arranged around the transfer member, each of the color stations including a photoreceptor drum on which toner image layers are formed, the photoreceptor drum being electrically biased relative to the surface of the transfer member, the toner image layers being transferred from the photoreceptor drum and the surface of the transfer member at a first transfer nip and transferred from the transfer member to a sheet of print media at a second transfer nip;

a fuser;
at least one of:
a pre-marking station, located upstream of the main marking station, which prints a toner image layer on an associated sheet of print media, and
a post-marking station, located downstream of the main marking station, which prints a toner image layer on the associated sheet of print media, whereby a toner image is formed on the associated sheet from two or more toner image layers printed by the main marking station and the at least one of the pre-marking station and the post-marking station; and

a print media path connecting the main marking station and the at least one of the pre-marking station and post-marking station with the fuser.
