より本発明を説明する。However, if the above-mentioned resin dissolves too much in the developer carrier, it will cause image blurring, so in order to adjust the solubility of the above-mentioned resin, in addition to the above-mentioned resin, it is necessary to add a material that does not dissolve or is difficult to dissolve in paraffinic hydrocarbons. A resin can be added to the anchoring layer. Such a resin is preferably used for the dielectric layer, and adjusts the solubility of the fixing layer, and
Improves adhesion with dielectric layer. Examples of such resins include acrylic, polyester, copolymers such as vinyl chloride vinegar, and polyvinyl butyral. Such a resin can be added within a range that does not prevent the characteristics of the soluble (swellable) resin, and is usually less than 40%.The present invention will be explained with reference to the examples shown in the drawings.

ごれのない優れた画像を得ることができる。[Effects of the Invention] As is clear from the above examples, in the electrostatic recording material of the present invention, toner fixing properties are significantly improved because a layer with a constant orientation of 1 to 4 times is provided on the dielectric layer. However, by using the image-formed product, it is possible to obtain an excellent image without the image falling off due to rubbing during handling and without staining around the image.
