Image forming apparatus having intermediate tray

Abstract

An image forming apparatus includes an intermediate tray wherein a copied paper on which an image has been formed is stored. In the case of a double-face copy, the copied paper is stored in the intermediate tray in a manner that a surface on which an image has been formed is faced upward and, in the case of a multi-copy, the copied paper is stored in the intermediate tray in a manner that a surface on which an image has been formed is faced downward. The intermediate tray has two movable guide members which sandwiches the copied paper stored in the intermediate tray in a width direction thereof. The movable guide members are moved so as to go and come back once at every timing when a sheet of copied paper is stored in the intermediate tray, whereby both side ends of the copied paper are pushed by the movable guide members to be aligned. The movable guide members are returned to respective home positions at every timing when ten copied papers are stored in the intermediate tray, whereby an accumulative error of the movement of the movable guide members can be corrected. In addition, a center position between the two movable guide members can be electrically corrected by moving respective reference positions of the movable guide members in the same direction at the same amount.
