Abstract
A cleaning device includes a cleaning unit which includes a web; a first roller, a second roller for winding the web up, a driving mechanism for second roller, a third roller urging the web to the rotatable member, an urging portion urging the third roller toward the rotatable member, and a supporter supporting the third roller while permitting movement relative to the first and second rollers; a moving mechanism for relative movement between the cleaning unit and the rotatable member, between a first position in which the web is spaced from the rotatable member and a second position in which they contact; and a controller. When the mechanism causes the relative movement from the first position to the second position, the controller operates the mechanism for a predetermined duration to substantially eliminate the slackness of the web resulting from the relative movement.
