To provide a gear rolling method using circular dies, capable of producing teeth of an appropriate shape while causing no movement during processing.

A work piece 3 having a cylindrical outer surface is supported on a support part 5 in such a manner as to be freely rotatable around the rotational axis X of the cylindrical outer surface, and a pair of circular dies 1 rotating around an axis parallel to the rotational axis X are arranged in opposition to one another across the work piece 3. The pair of circular dies 1 are pressed against the work piece 3 while synchronously controlling the rotational speed and pressing amount thereof by a drive mechanism. The outer diameter of the work piece 3 is set such that when the rotational state wherein the circular dies 1 and the work piece 3 rotate together changes, from a friction wheel state that is based on the mutual pressing forces, to a toothed wheel state that is based on the engagement of the work piece 3 and the circular dies 1, with a tooth groove being formed in the work piece 3 by the pressing of the circular dies 1, the length when the outer circumferential length of the bottom of the tooth groove is divided by the number of teeth to be formed is identical to the addendum circle pitch of the circular dies 1.
