Device and method for recording image to electronic paper

A method for recording an image on electronic paper, comprising:

• supplying electronic paper in a gap between an image support body that supports a latent image and an opposing member facing the image support body, the electronic paper having charged color particles and being used for displaying an image as a result of charged color particles migrating in a thickness direction, the image support body including a photoreceptor;
• irradiating laser light to the photoreceptor in order to for the latent image;
• and
• displaying an image that corresponds to the latent image on the electronic paper by applying voltage to the opposing member, controlling the voltage applied to the opposing member so that the value of the voltage varies together with time, generating an electric field in the gap along the thickness direction, and causing the charged color particles to move in the thickness direction.

A device for recording an image onto electronic paper, comprising:

• an image support body that supports a latent image, the image support body including a photoreceptor, the image support body configured to form the latent image by irradiating laser light to the photoreceptor;
• an opposing member that faces the image support body;
• a conveyance member that conveys electronic paper that has charged color particles and that displays an image as a result of the charged color particles migrating in a thickness direction;
• a voltage-applying section that applies voltage to the opposing member when the electronic paper is positioned between the image support body and the opposing member, where an electric field is generated along the thickness direction in the gap, and the charged color particles are caused to move in the thickness direction, where an image corresponding to the latent image is displayed on the electronic paper;
• and
• a controller that causes the voltage-applying section to carry out a first process for causing the electronic paper to be conveyed to the conveyance member, causes mutually different locations of the electronic paper to be sequentially fed to the gap, causes an image corresponding to the latent image to be sequentially displayed in the location fed to the gap, causes the voltage-applying section to carry out a second process for causing the electronic paper to be conveyed to the conveyance member, causes the locations having just come out from the gap to again be sequentially fed to the gap, and causes the image corresponding to the latent image in the location fed to the gap to again be sequentially displayed, wherein
• the controller controls the voltage applied to the opposing member so that the value of the voltage is a constant value when the first process has been carried out, and controls the voltage so that the value of the voltage varies together with time when the second process is carried out.
