Abstract
A transfer apparatus includes a transfer belt that has a volume resistivity of 109 to 1012 Ω·cm and carries a liquid developer including a carrier liquid and toner particles with conductivity equal to or greater than 1 pS/cm and equal to or less than 100 pS/cm in a first surface thereof. A first roller is grounded and is in contact with a second surface of the transfer belt. A second roller is in contact with the second surface of the transfer belt. A third roller is in contact with the first surface of the transfer belt and presses the first roller with the transfer belt interposed therebetween. A voltage source applies a voltage to the third roller.
Claims8
A transfer apparatus comprising:
- a transfer belt that has a volume resistivity of 109 to 1012 Ω·cm and carries a liquid developer including a carrier liquid and toner particles with conductivity equal to or greater than 1 pS/cm and equal to or less than 100 pS/cm in a first surface thereof;
- a first roller that is grounded and is in contact with a second surface of the transfer belt;
- a second roller that is in contact with the second surface of the transfer belt;
- a third roller that is in contact with the first surface of the transfer belt and presses the first roller with the transfer belt interposed therebetween;
- and
- a voltage source that applies a voltage to the third roller.
An image forming apparatus comprising:
- a latent image carrier on which a latent image is formed;
- a charging unit that charges the latent image carrier;
- an exposure unit that forms the latent image on the latent image carrier charged by the charging unit;
- a development unit that develops the latent image formed on the latent image carrier by the exposure unit using a liquid developer including a carrier liquid and toner particles with conductivity equal to or greater than 1 pS/cm and equal to or less than 100 pS/cm;
- a transfer belt with a volume resistivity of 109 to 1012 Ω·cm, in which an image developed by the development unit is transferred on a first surface thereof;
- a first roller that is grounded and is in contact with a second surface of the transfer belt;
- a second roller that is in contact with the second surface of the transfer belt;
- a third roller that is in contact with the first surface of the transfer belt and presses the first roller with the transfer belt interposed therebetween so as to transfer the image on a recording medium;
- and
- a voltage source that applies a voltage to the third roller.
