Abstract:
A cleaning device for cleaning a moving surface of a cleaning target includes a laminated blade member including multiple layers including a proximal edge layer, each of the multiple layers made of materials different in permanent set value and a holding member to hold a distal end of the blade member. A proximal edge portion of the blade member at a free, leading end opposite the distal end of the blade member held by the holding member brought into contact with the surface of the cleaning target to clean the surface undergoes a linear pressure reduction rate of approximately 90% or higher.
