Abstract
Electrophotographic marking machines having imageable seam intermediate transfer belts. A toner image is produced on a charged photoreceptor. That image is then transferred onto a seamed intermediate transfer belt without regard as to the relative position of the seam. The seam region has good electrical property correspondence with a far region away from the seam and a lateral resistivity greater than 108 ohms/square. That transferred toner image is subsequently transferred to a fusing member for fusing.
Claims30
A marking machine, comprising:
- a moving photoreceptor belt;
- a charging station for charging said photoreceptor belt;
- an imaging station for exposing said charged photoreceptor belt so as to produce a latent image;
- a developer for depositing toner on said latent image;
- a transfer station for transferring said deposited toner onto a substrate, said transfer station including a seamed intermediate transfer belt that receives toner from said imaging station;
- a fuser having a fusing member for receiving toner from said intermediate transfer belt and for fusing said transferred toner to said substrate;
- and
- a cleaning station for cleaning said photoreceptor;
- wherein said seamed intermediate transfer belt comprises a seamed substrate formed by joining ends of a belt at a seam, wherein said seamed substrate has a seam region around said seam and a far region away from said seam;
- and
- wherein said seam region has good electrical property correspondence with said far region, and wherein said seam and far regions have lateral resistivity greater than 108 ohms/square.
