摘要：
A first bearing member and a second bearing member fit in a first side and a second side of a rotating shaft in the axial direction, respectively. The first bearing member is held by a supporting portion provided in a casing on a side corresponding to an emplacing member of an image carrier drum. The second bearing member is held by fitting in a fit-in portion from inside. A wall surface that regulates a charging roller in a longitudinal direction is formed on the second bearing member to protrude from a wall surface rotatably and pivotally supporting the charging roller.
