Abstract

A method of forming fixed images includes charging a photoconductor; exposing the photoconductor to light; developing an electrostatic latent image, such that a toner is applied to the electrostatic latent image formed on a transfer film moving in partially close contact with the photoconductor to form a visible image; transferring the formed visible image onto a recording medium such as a recording paper; and fixing the transferred visible image onto the recording medium. The toner is an encapsulated toner, the photoconductor is a heat-resistant photoconductor, and the transfer process and the fixing process are simultaneously carried out on the surface of the heat-resistant photoconductor covered with the transfer film onto the preheated recording medium.

Dependent claims

A method of forming fixed images, comprising:

charging a heat-resistant photoconductor;
covering a surface of said heat-resistant photoconductor with a photopermeable transfer film;
exposing said transfer film and said heat-resistant photoconductor to light, thereby forming electrostatic latent images on the surface of said transfer film and said heat-resistant photoconductor;
developing said electrostatic latent images on the surface of said transfer film into a visible image by applying an encapsulated toner to said transfer film in the area of said electrostatic latent image;
simultaneously transferring said visible image onto a preheated recording medium and fixing the transferred visible image onto the recording medium by contacting said recording medium with the surface of said transfer film while said transfer film is in contact with the surface of said heat-resistant photoconductor.
