ABSTRACT:
There is provided a copying machine in which a copying magnification and a copying density are variable. When the operation mode is set in the check mode and a copying start key is depressed, a document is copied once at a predetermined copying magnification or copying density. Thereafter, the copying magnification or the copying density is automatically changed, and the copying operation of the document is performed again. The above-mentioned operation is repeated until the copying operations at all the copying magnifications or the copying densities are completed.
