ることを特徴とする像形成装置。 [Claims for Utility Model Registration] An image forming apparatus that forms an image on a fed member, which includes a path along which the member is transported, a transport means for transporting the member, and a jam of the member on the path. a plurality of jam detecting means; means for monitoring the number of members in the route based on the number of members fed to the route and the number of members discharged from the route; and a means for monitoring the number of members in the route based on the output from the jam detecting means. means for controlling the conveyance means to stop the conveyance of the members before the predetermined position and discharge the members after the predetermined position when the member jams before the predetermined position on the travel path; An image characterized by having means for subtracting the number of members ejected by the ejecting operation after jamming from the number of members in the path at the time of jamming by the monitoring means to output the number of members remaining in the path. Forming device.

Claims

[Claims for Utility Model Registration] (1) In an apparatus for forming an image on a fed member, when the member jams before a predetermined position on the path, the operation of the member feeding means before that position is stopped, and A safety device characterized by continuing the operation of the member feeding means after the position and detecting a jam in the member transferred by the continuation of the operation. (2) The safety device set forth in paragraph (1), wherein the predetermined position is a transfer station to the member. (3) The safety device set forth in item (1), wherein the predetermined position is a station that fixes a toner image on the member.
