<p>PURPOSE:To shorten copying time by constructing an image forming device in such a way as to perform so-called the first-out of the specified number of sheets from a second paper supply part and to supply the number of sheets, obtained after substracting the (nk) number of sheets from the number of copies, from a first paper supply part, thereby performing the copying process to the first copies through a short paper feed path. CONSTITUTION:A large volume of sheets supplied from a first paper supply part is conveyed to an image transfer part 1, to be exact, to a pair of paper supply timing rollers 208 positioned right in front of the image transfer part 1. Meanwhile, (nk) number of sheets supplied from a second paper supply part 3, in which the sheets of the same size are accommodated, pass the image transfer part 1 and are subjected to the copying process beforehand. After the copying process of (nk) number of sheets, the copying process is performed to the sheets supplied from the first paper supply part 4.</p> |
