Abstract
PURPOSE: To squeez the developer of the cleaning roller, by pressing said roller to the drum after finishing the copying work.
CONSTITUTION: The developer is supplied through 6 for cleaning and then sent back to the developing unit from the side of the blade 5. The cleaning roller 4 absorbs the developer on the drum to perform the cleaning. As the developer in the roller 4 is concentrated to increase the toner grain size and thus deteriorated, a downward displacement is given to the roller shaft 4a after copying to press the roller 4 to the drum, and thus the developer is squeezed. When the fixed rotation is over, the roller 4 is reset to its original position. The roller 4 has no malformation at all since it is press-contacted temporarily, at the same time also increasing the cleaning effect through the pressing.
