Developing roller and method of producing the same
Abstract:
There are provided a developing roller having no risks of the image density of formed images rapidly decreasing and the occurrence of an uneven density since a toner transportation amount does not decrease greatly even if image formation is repeated, and a method of producing the same. In a developing roller, a plurality of recesses are disposed on an outer circumferential surface of a roller main body so that a ratio PA/PC of a pitch PA in an axial direction on the outer circumferential surface to a pitch PC in a circumferential direction is set to a range exceeding 1.1. The production method includes a process of forming the recesses on the outer circumferential surface by laser processing.
