Abstract

PURPOSE:To obtain a roller which is high in its parallel degree and true circular degree in a simple and easy way without cutting, grinding and buffing, by repeatedly subjecting round rod-like slag of an Al alloy to cold forging, and after that, performing its heat treatment to prescribed hardness in the course of extrusion working before the final extrusion working. CONSTITUTION:For instance, when obtaining a body 1 of a backup roller of a printer, at first, round rod-like slab (a) of an Al alloy which is cut to prescribed dimensions is sized, and after that, extrusion forming of cold forging is repeated in order, and worked slag a' is obtained. It is subjected to heat treatment so as to be its hardness about >=HRB50. After that, it is formed by reduction-working, and a desired roller body 1 is obtained.
