Abstract
A cleaning device includes a first cleaning roller and a second cleaning roller. The first cleaning roller contacts a member to be cleaned and rotates, separates any matter to be removed that is stuck on the member to be cleaned from the member to be cleaned, and causes the matter to be removed to adhere to the first cleaning roller. The first cleaning roller has a diameter that decreases continuously from a center thereof towards both ends thereof in a direction of a rotation axis. The member to be cleaned rotates or circulates. The second cleaning roller contacts the first cleaning roller and rotates, separates the matter to be removed that is stuck on the first cleaning roller from the first cleaning roller, and causes the matter to be removed to adhere to the second cleaning roller.
