摘要： An image forming method of the present invention comprises: a first toner image formation process for forming a first toner image by forming, on a latent image carrier, a first latent image which corresponds to a first image and developing the first latent image by a first toner charged to one polarity through a development selected from normal and reverse developments so as to correspond to the polarity of the first toner; a second toner image formation process for forming a second toner image by forming, on the latent image carrier, a second latent image which corresponds to a second image and developing the second latent image by a second toner charged to the other polarity by the other development while applying a developing bias; and a transfer treatment process for simultaneously transferring said first and second toner images to a transfer medium; wherein said developing bias VB2 satisfies the following equations:
|VT1 - VB2| > |VH2 - VB2| (1)
|VT1 - VB2| > |VT1 - VH2| (2)
where a surface potential of said first toner image is VT1, a background potential in said second toner image forming process is VH2, and the developing bias in said second toner image forming process is VB2.-
