The downstream cleaning member has an Asker C hardness of 28 degrees or more and 45 degrees or less. The cleaning device according to any one of claims 1 to 8,
The cleaning device, wherein the surface of the downstream cleaning member is a sponge having a cell diameter of 150 μm or less. The cleaning device according to any one of claims 1 to 9,
The cleaning device, wherein the recovery member is rotated around the downstream cleaning member. The cleaning device according to any one of claims 1 to 10,
Two cleaning members are provided on the upstream side in the moving direction of the object to be cleaned with respect to the downstream cleaning member,
One cleaning member is a cleaning brush roller that electrostatically removes positively charged toner on the object to be cleaned. The other cleaning member electrostatically removes negatively charged toner on the object to be cleaned. A cleaning brush roller that removes automatically. An image carrier for carrying a toner image;
Toner image forming means for forming a toner image on the surface of the image carrier;
Transfer means for transferring the toner image formed on the surface of the image carrier to a transfer member;
In an image forming apparatus comprising: cleaning means for cleaning the surface by scraping off the toner that is attached to the surface of the image carrier;
An image forming apparatus using the cleaning device according to claim 1 as the cleaning unit.
