An image formation apparatus contains ( 1 ) an image substrate, ( 2 ) a rotating unit that rotates the image substrate, ( 3 ) a bias applying unit which applies a charge bias to the image substrate, ( 4 ) a development unit that supplies a toner onto the image substrate, and ( 5 ) a cleaning blade that removes the material deposited on the image substrate, and the image formation apparatus is used for a deposit removal operation which is performed at a predetermined time while no charge bias is applied. The deposit removal operation includes rotating the image substrate, supplying the toner to the image substrate to an extent that an upcurve of the cleaning blade is not caused, and removing the deposited material. |
