<p>A cleaning device (16Y) includes a brush roller (162Y) that removes deposit from a surface of a member (15Y) to be cleaned while rotating by following a movement of the surface of the member to be cleaned. The brush roller includes a rotary shaft element (160Y) and a brush (161Y) provided on the rotary shaft element. The brush abuts the surface of the member to be cleaned due to a weight of the brush roller. The brush includes slanted filaments, and the brush roller satisfies a following inequation, Y / X ≤ 2.8, where Y is the diameter denier of each of the filaments, and X is length in mm of each of the filaments.</p> |
