PURPOSE:To prevent generation of a transfer member being soiled by developer by installing a means which detects the passage of a recoding material at a specified point in a recording member carrying path from a recording material feeding means part to a transfer position. CONSTITUTION:When the non existance of the recording material 14 is detected by the detecting means 15 and 16 while the recording material is being carried, an image forming process mechanism is controlled to inhibit the image forming operation to the recording material 14 immediately or after a specified time has passed, while the carrying operation is continued. Therefore, in a state where the recording material does not exist in the transfer position and the transfer member 9 is in direct contact with an image carrier 1 surface, the formation of a transferrable image on the image carrier 1 surface which is passed through the transfer position is inhibited and does not exist, or even when it is formed, it is controlled so that transferring of a transferrable image to the transfer material 9 is in a state of being stopped. Thus, even when the transfer material 9 is in a state of direct contact with the image carrier 1 surface, the situation where the developer of the transferrable image is adhered to the transfer material 9 making it solied is prevented. |
