Abstract
There is provided a cleaning device for an image-forming device configured so as to be capable of preventing the image quality from deteriorating by being able to prevent the deterioration of the charging state caused by deposits of foreign matter without increasing costs. There is also provided a cleaning member that can make contact with the cleaning target-members. The cleaning member has a portion composed of melamine resin foam for making contact with at least the cleaning target members, and the melamine resin foam has an Asker F hardness of 5 to 25 points and a hardness variation of 5 points or less, and is used on the cleaning target members in a state obtained by heat compression from the original shape. The pressing member is furthermore disposed in contact with the cleaning member.
