Abstract
In order to manufacture a discharging roller which discharges a recording medium from a recording apparatus, there are a first die formed with a first recess extending in an axial direction of a shaft portion of the discharging roller, and a second die formed with a second recess extending in the axial direction. The first die and the second die are combined such that the first recess and the second recess face to form a continuous cavity. Synthetic resin is injected into the cavity to mold a bore portion of the shaft portion.
