項に記載の画像形成装置。[Scope of claims for utility model registration] (1) An image carrier that carries a toner image and moves;
A transfer material that moves in synchronization with the movement of the image carrier includes a transfer unit that is provided in a transfer section that contacts the image carrier and transfers the toner image to the transfer material, and a pair of rotating fixing rolls. a fixing unit that fixes the toner image on the transfer material by sandwiching the transfer material on which the toner image has been transferred between the fixing rolls; A conveying means for conveying the transfer material to the fixing section without passing through another conveyance means, and a concavely curved guide member for guiding the transfer material from the transfer section to the fixing section, An image forming apparatus characterized in that the moving speed of the image carrier is set faster than the moving speed of the image carrier. (2) The moving speed of the image carrier is V, the circumferential speed of the fixing roll is V + Δv, and the front edge of the transfer material between the transfer section and the fixing section when the leading edge of the transfer material reaches the fixing means. When the length is L 1 , the linear distance from the transfer section to the fixing section is L 2 , and the maximum length of usable transfer material is L 0 , the value of Δv is Δv<L 1 −L 2 L 0 - The first claim for utility model registration, which is characterized by being set within the range of L 1 V.
The image forming apparatus described in .
