A cleaning device for cleaning an image forming surface of a rotating image bearing member that bears a toner image includes a cleaning member that faces and cleans the image forming surface. An operating mechanism allows the cleaning member to come in press-contact with and separate from the image forming surface. A controller controls the operating mechanism. A solid lubricant provides lubricity to the image forming surface through the cleaning member. The solid lubricant contacts of cleaning member in a state where the cleaning member is in press-contact with the image forming surface and the solid lubricant separates from the cleaning member in a state where the cleaning member separates from the image forming surface.

1. Field of the Invention
The present invention relates to cleaning devices provided in image forming apparatuses such as copying machines, printers, and facsimile machines, and image forming apparatuses provided with the same.
2. Description of the Related Art
FIG. 1 shows a schematic configuration of a printer in accordance with an embodiment of the present invention.
FIG. 2 is a perspective view showing a state where an intermediate transferring unit and a cleaning unit are dismounted from the printer shown in FIG. 1.
FIG. 3 is a perspective view of the cleaning unit.
FIG. 1 shows a schematic configuration of a printer 1 (image forming apparatus) in accordance with an embodiment of the present invention. A right side in the drawing corresponds to a front side of the printer 1, and a left side corresponds to a back side.
In an apparatus main body 2 of the printer 1, there is provided an image forming section 3 having a photoconductive drum 4. On an outer peripheral surface of the photoconductive drum 4, a layer of a photoconductive member made of, for example, amorphous silicon is formed. The photoconductive drum 4 is rotated in a counter-clockwise direction in FIG. 1, and a series of operations including forming of an electrostatic latent image, developing of an electrostatic latent image by toners, and primary transferring of a toner image is performed on the outer peripheral surface.
In particular, in periphery of the photoconductive drum 4, there is provided a charging device 6 which comes close to an upper position of the photoconductive drum 4. The charging device 6 charges the outer peripheral surface of the photoconductive drum 4. In a state where the photoconductive drum 4 is charged, a scanning light is irradiated from a laser scanning unit 8 to the outer peripheral surface.
