Abstract
The invention is an apparatus for continuously removing excess carrier liquid from a photoreceptor comprising an image drying means which contacts the photoreceptor, wherein the image drying means has an outer layer which absorbs and desorbs carrier liquid and an inner layer having a Shore A hardness of 10 to 60 which is phobic to the carrier liquid, and a heating means which heats the surface of the image drying means for at least 0.05 seconds to no more than 5.degree. C. below the flashpoint of the carrier liquid, wherein the photoreceptor is moving at a speed of greater than 45 mm/sec. The invention is also the method of removing excess carrier liquid from a photoreceptor comprising contacting the photoreceptor with such a drying element and then heating the drying element to no more than 5.degree. C. below the flashpoint of the carrier liquid for at least 0.05 seconds.
