(従来の技術)
画像形成技術の分野において、−様に帯電させた感光体
上に画像信号に応じて選択的に光照射を行い、形成され
た静電潜像を現像する方式は一般に静電写真プロセスと
呼ばれている。この静電写真プロセスには大別して乾式
現像法と湿式現像法とがある。(Prior Art) In the field of image forming technology, a method in which light is selectively irradiated onto a negatively charged photoreceptor according to an image signal and the formed electrostatic latent image is developed is generally an electrostatic latent image. It's called the photographic process. This electrostatic photographic process can be roughly divided into a dry developing method and a wet developing method.

いる。Among these, the wet development method uses a liquid developer in which a dye or pigment as a coloring agent is dispersed in the form of fine particles in an insulating medium. According to the wet development method, it is possible to obtain resolution and gradation comparable to silver halide photography, and the weather resistance of the formed image is excellent, especially when pigments are used as colorants. Development is progressing in all directions.

分散されてなる静電潜像現像剤を開示している。In addition, the applicant of the present application previously filed a patent application filed in Japanese Patent Application No. 63-156 to improve the storage stability and handling properties of the above-mentioned liquid developer.
No. 846 discloses an electrostatic latent image developer in which colorant particles are dispersed in an electrically insulating organic compound that is solid at room temperature and has an average molecular weight of 12,000 or less.

求する画像形成の目的には必ずしも適したものではなか
った。By the way, in order to record and preserve the electrostatic latent image developed as described above in a readily visible form, it is preferable to transfer it to a suitable transfer object. However, in the conventional wet development method, the adsorption between the colorant particles and the photoreceptor is too strong, resulting in a decrease in transfer efficiency, and the method is not necessarily suitable for the purpose of image formation in pursuit of high image quality.

た用途に適用されているのみである。In contrast, image forming methods that do not involve transfer, such as so-called electro-fax, have also been proposed. This is a method of directly forming an image on a transparent photoreceptor such as polyvinyl carbazole or a white photoreceptor such as ZnO. However, since the amount of sensitizing dye used is naturally limited due to the need to maintain appropriate transparency or whiteness of the photoreceptor, it is difficult to improve sensitivity and there is a limit to speeding up image formation and readout. Furthermore, there are disadvantages such as low dispersion stability of the colorant and high cost as the photoreceptor cannot be reused since no transfer is performed. It is only applied to limited uses such as
