PROBLEM TO BE SOLVED: To make an applying roll being provided with property letting statically charged toner particles possible to effectively and possible to control permissibly stuck on an outside face of the applying roll, as well as an optical transmission member being provided with the electrostatic property required for feeding the toner particles, and moreover to make the static property of the applying roll equalized as well as being possible to be adjustable. SOLUTION: This roll 154 is constituted to incorporate a core 1541, and the outside face coating film 1542 incorporating stabilizing zirconia in the core. The outside face coating 1542 is, furnished with smooth finishings and the controlled static property. The outside face coating 1542 on this roll 154 is, made possible to be finished to a very smooth finishing with the short cycle time. |
