ABSTRACT:
An image forming apparatus such as a copying machine includes an image forming section for forming an image on a sheet of paper. In the image forming apparatus, a paper supporting member supports a stack of papers, and an elevator is provided for raising and lowering the paper supporting member. Further, a paper feeder feeds a sheet of paper from the paper supporting member to the image forming section. When an operation key is depressed, the image forming section is instructed to start forming an image. A controller controls the image forming section to form an image on a sheet of paper when the paper feeder can feed a sheet of paper if the operation key is depressed during rising of the paper supporting member.
