摘要

A developing apparatus (11) of the type including a developing roller (17) disposed in a development box, a stirring roller (15) parallel spaced apart from the developing roller (17), and a toner replenisher pipe (19) disposed in the stirring roller (15), wherein the stirring roller (15) has a substantially hollow cylindrical shape and includes a plurality of axial ribs (15a) extending parallel to a longitudinal axis of the stirring roller (15) and disposed equidistantly from the longitudinal axis, and a plurality of helical blades (15b) integral with the axial ribs (15a) and skewed relative to the longitudinal axis of the stirring roller (15), said hollow cylindrical stirring roller (15) being composed of at least two identical segments which are divided by a plane extending through said longitudinal axis of said stirring roller (15). The stirring roller (15) is simple in construction and can be manufactured at a low cost.
