ABSTRACT:
An image forming apparatus includes: an image holder; a charging unit that charges the image holder; a latent image forming unit; a developing unit that forms a toner image; a transfer unit that transfers the toner image formed on the surface of the image holder onto a recording medium; a toner-particle removal unit that removes toner particles remaining on the surface of the image holder after the transfer of the toner image by the transfer unit; and an external-additive removal unit that includes a conductive blade disposed to contact the surface of the image holder and removes, after the transfer of the toner image by the transfer unit, external additive remaining on the surface of the image holder using the conductive blade while applying a voltage to the surface of the image holder via the conductive blade.
