る画像形成装置。[Claims for Utility Model Registration] A transfer charging method in which a transfer material is moved while being in contact with a curved portion of a latent image carrier, and the transfer material is stretched from behind the transfer material in approximately the axial direction of the latent image carrier. By causing corona discharge with the charge wire of the device, the toner image on the latent image carrier is transferred to the transfer material,
In an image forming apparatus that performs fixing by passing the transfer material between a pair of fixing rollers provided in the traveling direction of the transfer material after transfer, from the nip portion of the pair of fixing rollers, almost the surface of the curvature part is An image forming apparatus characterized in that the charge wire is provided directly below a tangent to the latent image carrier extending toward the latent image carrier and a contact point with the latent image carrier.
