Abstract
A developing roller includes: a magnet roller including a roll part with a magnetic pole; a cylindrical sleeve that houses the magnet roller; a first flange connected to one end of the sleeve; a second flange connected to another end of the sleeve; a conductive shaft connected to a side of the second flange of the magnet roller; a first bearing that supports the first flange so that the first flange rotates relative to the magnet roller; and second bearings that support the second flange so that the second flange rotates relative to the conductive shaft. The second bearings are conductive, and are disposed at different positions along an axial direction of the conductive shaft.
