Patent ID: 8139982

Claim:
An image formation apparatus comprising a first toner image-forming unit, a second toner image-forming unit and a fixing unit, the first toner image-forming unit comprising: a first electrostatic latent image holder; a first electrostatic latent image forming unit that forms a first electrostatic latent image on the surface of the first electrostatic latent image holder; a first developing unit that develops, with a first developer comprising a first toner, the first electrostatic latent image to form a first toner image; and a first transferring unit that transfers the first toner image to a recording medium so that the first toner image directly contacts a surface of the recording medium, the second toner image-forming unit comprising: a second electrostatic latent image holder; a second electrostatic latent image forming unit that forms a second electrostatic latent image on the surface of the second electrostatic latent image holder; a second developing unit that develops, with a second developer comprising a second toner, the second electrostatic latent image to form a second toner image; and a second transferring unit that transfers the second toner image to the recording medium so that the second toner image is disposed on the first toner image without directly contacting the recording medium, the fixing unit fixing the transferred first toner image and the transferred second toner image on the surface of the recording medium, and a contact angle θ 1 , that is the contact angle of the first toner with respect to an aqueous de-inking solution, being smaller than a contact angle θ 2 , that is the contact angle of the second toner with respect to the aqueous de-inking solution.
