Abstract
The present invention is directed to improvement in an image recorder for recording developed images or toner images by microwave fixation. According to the invention there is used a novel thermoplastic developer comprising of two components. The first component contains a dielectric material which is able to absorb microwave and generate heat by dielectric loss. The second component contains magnetic loss exothermic material. The microwave absorbing power of the first component is improved by heating the first component with heat generated from the second component.
Claims27
An image recording apparatus with microwave fixation comprising:
- means for forming a developed image on a recording material, said developed image being formed by a thermoplastic developer having a mixture of a first component and a second component, said first component being a dielectric material having the property of increasing microwave absorption efficiency as the temperature of said first component increases and capable of generating heat by dielectric loss when microwave energy is absorbed, said second component being a magnetic material capable of generating heat by magnetic loss so as to heat said first component to advance the microwave absorption efficiency of said first component and to concentrate the microwave energy itself on said developed image;
- and
- means for applying microwave energy to the recording material bearing said developed image and for microwave fixing said developed image onto said recording material.
