Abstract

A cleaning device includes a removal member that removes residual objects from a surface of a target cleaning body by contacting with the surface in a linear manner and rubbing against the surface and forms a piled body which is constructed of a portion of the residual objects at a contact location, and a pressure device that presses the piled body to increase a strength of the piled body.

First claim

What is claimed is:

1. A cleaning device comprising:
a removal member that removes residual objects from a surface of a target cleaning body by contacting with the surface in a linear manner and rubbing against the surface and forms a piled body which is constructed of a portion of the residual objects at a contact location; and
a pressure device that presses the piled body to increase a strength of the piled body,
wherein the residual objects contain particles which include oil content, and
wherein the pressure device presses the piled body with a pressure of larger than or equal to an extent at which the oil content seeps out from the particles.

2. The cleaning device according to claim 1 ,
wherein the residual objects contain particles for forming an image on a surface of the target cleaning body, and an external additive that is mixed with the particles for forming the image and that has a particle diameter that is smaller than a particle diameter of the particles for forming the image, and
wherein the cleaning device further comprises a reduction unit that reduces components other than the external additive in the residual objects before being pressed by the pressure device.

3. The cleaning device according to claim 1 ,
wherein the residual objects contain toner and an external additive treated with silicone oil.

4. An image forming apparatus comprising:
an image holding body that holds images formed on a surface;
an image formation unit that forms the images;
a transfer unit that transfers the images onto a recording medium from the image holding body;
a removal member that removes residual objects from a surface of the image holding body by contacting with the surface in a linear manner and rubbing against the surface and forms a piled body which is constructed of a portion of the residual objects at a contact location and; and
a pressure device that presses the piled body to increase a strength of the piled body,
wherein the residual objects contain particles which include oil content, and
wherein the pressure device presses the piled body with a pressure of larger than or equal to an extent at which the oil content seeps out from the particles.

5. The image forming apparatus according to claim 4 ,
wherein the residual objects contain particles for forming the images on a surface of the image holding body, and an external additive that is mixed with the particles for forming the images and that has a particle diameter that is smaller than a particle diameter of the particles for forming the images, and
wherein the image forming apparatus further comprises a reduction unit that reduces components other than the external additive in the residual objects before being pressed by the pressure device.
