<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus which sets a transfer current according to the percentage of toner images with weak electrostatic charge amount of toner images on a photosensitive body in order to suppress the generation of dust and unevenness of an image. <P>SOLUTION: The image forming apparatus 1 charges the photosensitive body 10, forms an electrostatic latent image by exposing the photosensitive body 10, forms the toner image by adhering charge toner to the electrostatic latent image on the photosensitive body 10 and transfers the toner image on the photosensitive body 10 to transfer paper. Furthermore, the image forming apparatus 1 has a detection means 25 detecting toner amount on the photosensitive body and a detection means 24 of detecting potential on the surface of the photosensitive body provided in down stream from a developing device 7, creates a plurality of different reference images on the photosensitive body 10, calculates the percentage of weak electrostatic charge amount of the toner on the photosensitive body from a detection value of the detection means 25 of toner amount on the photosensitive body and a detection value of the detection means 24 detecting potential on the surface of the photosensitive body and controls transfer output conditions of a transfer device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
