    Abstract: An electrostatic copying apparatus and an auxiliary unit detachably mounted on the electrostatic copying apparatus to diversify the mode of image formation. The electrostatic copying apparatus includes a paper conveying passage, a paper feed means for feeding paper to the paper conveying passage and a paper feed passage having its downstream end connected to the paper conveying passage, and a copied image is formed on one surface of paper while it is conveyed through the paper conveying passage after being introduced into the conveying passage from the paper feed means or the paper feed passage. The auxiliary unit includes a paper moving passage whose upstream end is to be selectively connected to the downstream end of the paper conveying passage of the copying apparatus and a paper stock means whose upstream end is connected to the downstream end of the paper moving passage and whose downstream end is connected to the upstream end of the paper feed passage of the copying apparatus. The copying paper introduced into the paper conveying passage from the paper feed means in the electrostatic copying apparatus and conveyed through the paper conveying passage is selectively introduced into the paper moving passage of the auxiliary unit and then fed into the paper stock means of the auxiliary unit. Thereafter, the paper is introduced into the paper conveying passage of the copying apparatus from the paper stock means via the paper feed passage of the copying apparatus.
