Abstract:
An image formation apparatus which includes a rotating image-bearing body, a charging section, an exposure section, a developing section, a transfer section, and a residue toner-charging section. The charging section charges the image-bearing body. The exposure section forms an electrostatic latent image on the image-bearing body that has been charged. The developing section develops the electrostatic latent image and forms a toner image. The transfer section transfers the toner image to a transfer body. The residue toner-charging section is provided upstream of the charging section and downstream of the transfer section and, after the transfer, charges transfer residue toner to a normal polarity. The transfer residue toner that has been charged to the normal polarity by the residue toner-charging section is recycled at the developing section. The residue toner-charging section is provided with a nonwoven fabric, which features conductivity and touches against the image-bearing body.
