IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD

摘要

An image forming apparatus includes a paper type detection unit, a paper type determination unit, a paper search unit, and a paper change unit. The paper type detection unit detects a type of a paper conveyed from a paper feeding cassette by a sensor. The paper type determination unit determines whether there is a change in the type of the paper during the printing. The paper search unit searches whether there is an appropriate paper feeding cassette for accommodating papers having paper types equal to types of papers before paper types are changed when there is a change in the type of the paper during the printing as a result of the determination. The paper change unit processes the paper with the changed type and resumes conveyance of papers from the existing appropriate paper feeding cassette when there is the appropriate paper feeding cassette as a result of the search.
