Abstract
An apparatus for transporting marking particles is provided. The apparatus includes a donor roll and an electrode member. The electrode member includes a plurality of electrical conductors mounted on the surface of donor roll with adjacent electrical conductors being spaced from one another. The electrode member further includes a connecting member fixedly secured to the donor roll. The connecting member electrically interconnects at least two electrical conductors.
Claims16
An apparatus for transporting marking particles, comprising:
- a donor roll;
- an electrode member including a plurality of electrical conductors mounted on the surface of donor roll with adjacent electrical conductors being spaced from one another;
- and
- a plurality of spaced apart connecting members fixedly secured to said donor roll proximate a first end of said donor roll, each of said connecting members electrically interconnecting at least two electrical conductors, said connecting members being electrically isolated from each other.
A developer unit for developing a latent image recorded on an image receiving member to form a developed image, said developer unit adaptable for use with a power source for providing an electrical bias to said developer unit, said developer unit comprising:
- a donor roll;
- an electrode member including a plurality of electrical conductors mounted on the surface of donor roll with adjacent electrical conductors being spaced from one another;
- and
- a plurality of spaced apart connecting members fixedly secured to said donor roll proximate a first end of said donor roll, each of said connecting members electrically interconnecting at least two electrical conductors, said connecting members being electrically isolated from each other so that said connecting members may selectively receive the electrical bias.
An electrophotographic printing machine having a developer unit adapted to develop with marking particles an electrostatic latent image recorded on a photoconductive member, the machine comprising:
- a donor roll;
- an electrode member including a plurality of electrical conductors mounted on the surface of donor roll with adjacent electrical conductors being spaced from one another;
- and
- a plurality of spaced apart connecting members fixedly secured to said donor roll proximate a first end of said donor roll, each of said connecting members electrically interconnecting at least two electrical conductors, said connecting members being electrically isolated from each other so that said connecting members may selectively receive the electrical bias.
