Abstract
A method of evaluating electrophotographic overcoatability of a composition is provided. The method includes measuring a color (C1) of a toner image fixed on a sheet, dropping the composition on the toner image, and removing the composition from the toner image. The method further includes measuring a color (C2) of the toner image from which the composition has been removed, and calculating a color difference between the color (C1) of the toner image and the color (C2) of the toner image on which the composition is dropped and from which the composition is removed thereafter.
