Abstract:
1. A cleaning apparatus comprising: a blade which abuts on an image bearing member which bears a toner image, and removes toner which remains on the image bearing member; a first spiral spring which is disposed at one side portion of the blade in a longitudinal direction and is compressed to press the blade toward the image bearing member; a second spiral spring which is disposed symmetrically from the first spiral spring with respect to the center of the blade in the longitudinal direction and is compressed to press the blade toward the image bearing member; a first attachment portion which allows the first spiral spring to attach to an apparatus main body when the first spiral spring is positioned at a predetermined rotational orientation, and does not allow the first spiral spring to attach to the apparatus main body when the first spiral spring is positioned at a rotational orientation other than the predetermined rotational orientation; and a second attachment portion which allows the second spiral spring to attach to the apparatus main body when the second spiral spring is positioned at the predetermined rotational orientation, and does not allow the second spiral spring to attach to the apparatus main body when the second spiral spring is positioned at a rotational orientation other than the predetermined rotational orientation.
