发明名称 Image forming method that switches from an empty paper cassette to a non-empty paper cassette
摘要 An image forming apparatus includes plural paper feed portions to feed paper and an image forming portion to form an image on paper fed from one of the plural feed portions. When paper in the paper feed portion which feeds paper on which the image is formed in the image forming portion of this image forming apparatus is exhausted, it is so controlled that paper is automatically fed to the image forming portion from another paper feed portion containing the same size paper as that contained in the current paper feed portion, enabling it to continue the image forming operation and it is possible to set whether the execution of the automatic paper feed control is permitted or prohibited for each of plural paper feed portions.
