Abstract

An image forming apparatus of the invention includes a carrier solution application roller that rotates centering on a rotary shaft and applies a carrier solution to a transfer roller after an image of a liquid developer including toner and the carrier solution is transferred to a transfer medium, a transfer roller cleaning roller, supported by a cleaning member support portion through a rotary shaft, which removes toner remaining in the transfer roller, and a carrier solution application roller of which the amount of movement is larger than the amount of movement of the transfer roller cleaning roller when the cleaning member support portion is rotated. Even when the transfer roller moves, satisfactory cleaning properties are secured without breaking a mutual positional relationship by facilitating mutual positioning between the transfer roller and the transfer roller cleaning roller.

Dependent claims

An image forming apparatus comprising:

a latent image carrier in which a latent image is formed;
an exposure portion that exposes the latent image carrier to form the latent image;
a development portion that develops the latent image formed in the latent image carrier using a liquid developer including toner and a carrier solution;
an image carrying roller to which an image developed in the development portion is transferred;
an application portion, having a cleaning solution application roller that applies a cleaning solution to the image carrying roller, which rotates through a first rotary shaft;
a cleaning portion, having a cleaning roller that comes into contact with the image carrying roller to which the cleaning solution is applied by the cleaning solution application roller and cleans the image carrying roller, which rotates through a second rotary shaft;
and
a cleaning member support portion that supports the application portion and the cleaning portion, and rotates through a third rotary shaft to move the cleaning solution application roller by an amount of movement larger than that of the cleaning roller.
