ABSTRACT:
A doctor blade for removing water, which excels in water removal capability and shape retention capacity, and suppresses abrasion of the belt or other mating member with which it cooperates, is a fibrous laminate comprising integrated base material and batt fiber layers. By impregnating resin into one side of the fibrous laminate, a layer in which the amount of impregnated resin is large and a layer in which the amount of impregnated resin is small are provided. In use, the layer in which the amount of resin is small is in contact with a belt or other mating member. The doctor blades can be adapted to the mating member easily, and excel in the water removal capability and shape retention, and suppress abrasion of the mating member.
