Claims

[Scope of utility model registration request]

A paper positioning member is provided between the paper feed cassette and the photoconductor, and this positioning member is held stationary at a predetermined position through which the paper normally passes, and the paper sent out from the paper feed cassette reaches the positioning member. Prior to this, the positioning member is moved to a position that prevents the paper from advancing, and the positioning member is returned to the original predetermined position at the timing when the paper and the toner image formed on the photoreceptor match. A paper feeding device for a compound gradient machine, characterized in that it is equipped with a device.
