Abstract
A cleaning device includes a first cleaning roller and a second cleaning roller. The first cleaning roller contacts a member to be cleaned, 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 member to be cleaned rotates or circulates. The first cleaning roller has an elastic peripheral surface. The second cleaning roller has a peripheral surface whose hardness is higher than that of the first cleaning roller. The second cleaning roller pushes the first cleaning roller and rotates while causing the first cleaning roller to be elastically recessed, to separate the matter to be removed that is stuck on the first cleaning roller therefrom and cause the matter to be removed to adhere to the second cleaning roller.
