Abstract
A liquid developer that comprises a colorant and a liquid for dispersing the colorant and serves to develop the latent image by causing the colorant to adhere to the latent image on the latent image carrier. The liquid comprises a first liquid comprising a photocurable liquid and a second liquid that is not mutually soluble with the photocurable liquid and comprises a liquid with a specific resistance higher than that of the photocurable liquid.
Claims18
A liquid developer for causing a colorant to adhere to a latent image on a latent image carrier and developing said latent image, comprising:
- a colorant;
- and
- a liquid for dispersing said colorant;
- wherein
- said liquid comprises a first liquid comprising a photocurable liquid and a second liquid that is not mutually soluble with said photocurable liquid and comprises a liquid with a specific resistance higher than that of said photocurable liquid.
An image forming method comprising a latent image carrier for carrying a latent image on the surface and a developer carrier for carrying a liquid developer on the surface and comprising the steps of causing the liquid developer sandwiched between said latent image carrier and said developer carrier to move to said latent image, forming an image on the latent image carrier, transferring said image to a recording medium, and fixing the image on said recording medium by irradiating the image transferred to said recording medium with light, wherein
- in the liquid developer comprising a colorant and a liquid for dispersing said colorant and serving to develop said latent image by causing said colorant to adhere to the latent image on the latent image carrier, said liquid comprises a first liquid comprising a photocurable liquid and a second liquid that is not mutually soluble with said photocurable liquid and comprises a liquid with a specific resistance higher than that of said photocurable liquid.
An image forming apparatus comprising a developing unit equipped with a latent image carrier for carrying a latent image on the surface and a developer carrier for carrying a liquid developer on the surface and forming an image on the latent image carrier by causing the liquid developer sandwiched between said latent image carrier and said developer carrier to move to said latent image, a transfer unit for transferring said image onto a recording medium, and a fixing unit for irradiating the image transferred to said recording medium with light and fixing the image on said recording medium, wherein
- in the liquid developer comprising a colorant and a liquid for dispersing said colorant and serving to develop said latent image by causing said colorant to adhere to the latent image on the latent image carrier, said liquid comprises a first liquid comprising a photocurable liquid and a second liquid that is not mutually soluble with said photocurable liquid and comprises a liquid with a specific resistance higher than that of said photocurable liquid.
A liquid developer container for accommodating inside thereof a liquid developer for developing a latent image formed on a latent image carrier, wherein
- in the liquid developer comprising a colorant and a liquid for dispersing said colorant and serving to develop said latent image by causing said colorant to adhere to the latent image on the latent image carrier, said liquid comprises a first liquid comprising a photocurable liquid and a second liquid that is not mutually soluble with said photocurable liquid and comprises a liquid with a specific resistance higher than that of said photocurable liquid.
