Abstract
A ceramic member includes a thin plate having a plurality of minute throughholes and a rigid plate supporting the thin plate. The area of the thin plate both ends of which are supported by the rigid plate has a part bent toward the rigid plate so that the line connecting the apexes of the bent part is a straight line, and minute throughholes are formed in the vicinity of the apexes of the bent part. Good adhesion between minute throughholes formed on the line connecting the apexes of the bent part and the drum and the like is obtained, and defective transfer can be prevented.
