摘要:
An image forming apparatus and method includes a first image-bearing member, a latent image-forming device for forming an electrostatic latent image on the first image-bearing member, developer for developing the electrostatic latent image with a toner to form a toner image, an intermediate transfer member for receiving the toner image by primary transfer and transferring the toner image onto a second image-bearing member by secondary transfer, a charging member for charging a residual toner remaining on the intermediate transfer member after the secondary transfer, and a recovery member for recovering the charged residual toner at a recovery position by voltage application. The intermediate transfer member exhibits a charging characteristic such that it has a surface potential of at most 500 volts as an absolute value at the recovery position. The intermediate transfer member having such a charging characteristic is effective in suppressing an occurrence of electric discharge at the recovery position of the residual toner to provide an excellent cleaning performance.
