Overcoat for imaging members.

摘要

A surface layer on an imaging member has a surface roughness which reduces the force necessary for blade cleaning, reduces blade edge tuck, reduces blade/substrate friction, inhibits the formation of toner-type deposits on the imaging surface, and/or reduces or eliminates light interference patterns resulting from coherent light, for example, from a raster output scanner. The surface roughness comprises a lateral roughness of between about 1 micrometer and about 200 micrometers, and a vertical roughness less than or equal to about 1 micrometer. The roughness may be defined by asperites formed by circulation patterns formed in the layer during drying or it may be defined by hemispheric dots of the overcoat layer formed during drying.
