Abstract
A blade of a cleaning device includes two surfaces: an upstream side surface and a downstream side surface. The two surfaces adjoin each other with respect to a contact edge of the blade. The upstream side surface has a longer dimension in the direction orthogonal to the contact edge than that of the downstream side surface. A horizontal portion of a blade holder that restricts a warp in the blade is bonded on an opposed surface to the upstream side surface of the blade. The blade is held via the horizontal portion with a vertical portion of the blade holder supported by the main body of the cleaning device in a downstream of a normal line to a contact point on a photoconductor surface in contact with the contact edge, in the photoconductor-surface moving direction.
