Patent ID: 7088941

Claim:
An image forming apparatus comprising: a photoconductor being movable for carrying a toner image; a transfer device, provided with a discharge wire, for transferring the toner image onto a transfer material through discharge from the discharge wire in a transfer area, after a transfer material is superposed with the photoconductor; a transfer-exposure device for carrying out light exposure of a surface of the photoconductor superposed with the transfer material from the back of the transfer material in the transfer area, the transfer area being an area where discharge from the discharge wire is applied onto the surface of the photoconductor; a separator for separating the transfer material from the photoconductor after the toner image is transferred; and a controller for controlling the operation of the image forming apparatus; wherein, distribution of an amount of light on the photoconductor surface from the transfer-exposure device, when the photoconductor surface superposed with the transfer material has reached the transfer area, is arranged such that an integrated value of an amount of exposed light upstream the point where the photoconductor surface is closest to the discharge wire, in a direction of movement of the photoconductor, is 10 through 30% of a total amount of exposed light from the transfer-exposure device, and the end of the exposed light in the upstream side on the photoconductor is within the transfer area.
