Abstract

A printed image after-processing apparatus is formed of a contact member which is coated with an excess ink removing solution which is incompatible with the printing ink forming a printed image and has a lower surface tension than the printing ink, and driven to rotate the contact member having coefficient of dynamic friction with 1.5 or less; a counter member holding to convey printed paper between it and the contact member, to thereby bring the printed surface of the printed paper into contact with the excess ink removing solution on the contact surface: a supplying device for supplying the excess ink removing solution to the contact member; and a cleaning device which contacts the contact member.
