Abstract: PURPOSE:To prevent an image from being uselessly formed by providing a means specifying the direction of the image formed on a recording material and inhibiting the modification of the direction of the image during a series of image forming actions. CONSTITUTION:After image information read in an original reader 10 is stored in a page memory 28, it is written in an optical magnetic disk device 12 through a data bus 24. Even if it is recorded on the recording paper, it is transferred to a recording device 14 through the memory 28. At the time of reading the image information to be recorded out of the memory 28 a reading start position at row and column addresses is modified, thereby modifying the direction of the recorded image. However, during forming the images of one file or one page, a control circuit 26 inhibits the direction of the image from being modified. Thus the formation of useless images if prevented. Simultaneously even if paper is bound and punched, such trouble can be previously prevented that the directions of images on pages differ and they cannot be bound or punched.

Abstract: PURPOSE:To prevent a recording material from being consumed uselessly by prioritizing a mode forming images on both sides of the recording material and carrying out processing when the number of formed images required as specified in a mode forming an image on the single side of the recording material. CONSTITUTION:Image information read-out by an original reader 10 is filed in an optical magnetic disk device 12, and its desired part is transferred to a recording device 14 if necessary. The device 14 forms the image of the image information transferred from the device 12 on the recording paper. In that case the number of formed images is specified in the mode forming an image on the single side of the recording material through an arrangement number key in the operation part of the device 14. If two images are formed per one side, the mode forming images on both sides is prioritized. Images are distributed to both sides of the recording material to form. Simultaneously a mode using mixed small-sized recording materials is selected and processing is made. Thus the waste of the recording material can be eliminated.
