Abstract

A cleaning device includes a brush roller that removes deposit from a surface of a member to be cleaned by rotating due to a movement of the surface of the member. The brush roller includes a rotary shaft element and a brush provided on the rotary shaft element. The brush abuts the surface of the member due to a weight of the brush roller. The brush includes filaments, and the brush roller satisfies the inequation Y/X≦2.8, where Y is a diameter (denier) of each of the filaments, and X is a length (mm) of each of the filaments. The filaments slant with respect to a normal direction of the rotary shaft element.
