Transfer device and image forming apparatus

Abstract

A transfer device includes an intermediate transfer member that has an outer peripheral surface to which a toner image is to be transferred, a primary transfer device that has a primary transfer member performing primary transfer of a toner image formed on a surface of an image holder to the outer peripheral surface of the intermediate transfer member, a secondary transfer device that has a secondary transfer member which is arranged in contact with the outer peripheral surface of the intermediate transfer member and performs secondary transfer of the toner image transferred to the outer peripheral surface of the intermediate transfer member to a surface of a recording medium, and a cleaning device that has a cleaning blade cleaning the outer peripheral surface of the intermediate transfer member, in which a coefficient D of dynamic friction between the intermediate transfer member and the cleaning blade is 0.2 or more and 1.2 or less, a lead-in angle A that a contact portion of the cleaning blade coming into contact with the intermediate transfer member forms with the intermediate transfer member is 15° or more and 80° or less, and the coefficient D of dynamic friction and the lead-in angle A satisfy Expression (1), lead-in angle A−(50×coefficient D of dynamic friction)>0  Expression (1).
