Abstract:
1. A wet type developing apparatus including a developing roller driven to rotate in rotational contact with a photoconductor drum and a cleaning roller driven to rotate in rotational contact with the developing roller whereby an electrostatic latent image formed on a surface of the photoconductor drum is developed into a toner image with a liquid developer applied to a surface of the developing roller in rotational contact with the photoconductor drum, characterized in that the wet type developing apparatus comprises: a set charger positioned so as to be opposite to a surface of the developing roller downstream of an area of rotational contact of the developing roller with the photoconductor drum in a rotation direction of the developing roller for applying negative charge to the surface of the developing roller; a liquid developer applying means disposed at one of: a first cleaning blade disposed in contact with a surface of the cleaning roller downstream of the area of rotational contact of the cleaning roller with the developing roller in the rotation direction of the cleaning roller; and a second cleaning blade disposed in contact with a surface of the developing roller downstream of the area of rotational contact of the cleaning roller with the developing roller in the rotation direction of the developing roller.
