Abstract
An enhanced or optimized cast-coated paper for enhancing or improving toner adhesion, and a method for forming an image on the enhanced or optimized cast-coated paper, includes a paper sheet with a coating solution on at least one surface of the paper sheet, the cast-coated paper having at least: a thermal diffusivity of less than approximately 9.0 mm2/s and total surface free energy component of less than 38 erg/cm2. Printing the cast-coated paper in an electrophotographic apparatus includes forming an image with an electrophotographic toner in the electrophotographic apparatus and transferring the image to the cast-coated paper having the thermal diffusivity of less than approximately 9.0 mm2/s and the total surface free energy component of less than 38 erg/cm2. The cast-coated paper may be used in apparatuses utilizing an electrophotographic process, such as a copying machine, a printer, a facsimile machine, a color-copying machine, and the like.
