Patent ID: 8538308

Claim:
An image forming device comprising: a rotation member having conductivity and being held rotatably while making contact with an image carrier; a rotation drive unit for rotating the rotation member; a solid lubricant pressed so as to make contact with the rotation member; a cleaning blade making contact with the image carrier so as to scrape off toner; and a potential application unit for applying a potential having the same polarity as the charged polarity of the image carrier to the rotation member, wherein a developing unit, a transfer unit, a neutralization unit, the rotation member and the cleaning blade are arranged in this order along the movement direction of the surface of the image carrier, the material of the solid lubricant and the material of the rotation member are selected so that the charged polarity of the solid lubricant charged due to the friction between the rotation member and the solid lubricant becomes identical with the charged polarity of the toner charged by the developing unit, the potential to be applied to the rotation member is set so as to be higher or lower than the surface potential of the neutralized image carrier so that the charges having the same polarity as the charged polarity of the solid lubricant are attracted from the rotation member to the neutralized image carrier, and the linear velocity of the rotation member is set so as to be lower than the linear velocity of the image carrier.
