Abstract
A cleaning device for cleaning an endless transfer belt which is made of elastic material and stretched between a first roller and a second roller, one of the two rollers being adapted for driving the belt, the transfer belt being able to come into contact with a copy sheet on one stretch side of the transfer belt to convey the copy sheet in a direction from the first roller to the second roller. The cleaning device is provided with a cleaning blade member for removing toner from the belt. The cleaning blade member is disposed on the other stretch side of the transfer belt and near the second roller, being pressed perpendicularly against an outside surface of the belt, and having a leading end portion which is flexed and capable of coming into a line contact with the belt over an entire width of the belt when the belt is driven. The amount of pressing force of the blade against the belt will be adjusted depending on the sensed temperature of the belt.
