Conveying roller, production method thereof and conveying apparatus

摘要

A conveying roller pair disposed in a bleaching-fixing bath of a photographic printer is constituted of a flat roller and a projection roller. Plural roller pieces are fixed to a roller shaft of the projection roller. Plural projections are formed by coating molding on an outer peripheral surface of the roller piece. Each roller piece has a core with an approximately ring shape, and an elastic layer with plural projections. The core and the elastic layer are adhered through a primer layer. Accordingly, uniform adhesive strength is secured and slipping of the elastic layer on the core is prevented. Since the plural projections are arranged in a phase-coherent manner, contact condition and contact pressure between the sheet and the projection roller are kept constant. As a result, a skew of the sheet is prevented.
