Abstract

PURPOSE:To obtain a toner electrostatically chargeable sufficiently and uniformly without scattering among the particles, and having stable characteristics in the system of an image developing means by incorporating a specified compd. as an electrostatic charge controller in the toner. CONSTITUTION:A toner contains as a charge controller a compd. represented by the formula as shown on the right in which R1, R2 are each NH or O; R3- R5 are each H, halogen, 1-5C alkyl, aralkyl, alkoxy, or acyl. Said compd. is alone or in combination of 2 kinds of said compds. preferably in an amt. of 1-20wt% of a binder resin, such as polymer of styrenes or vinyl esters.

A photosensitive layer in which an inorganic photoconductive material is dispersed in a binder resin is optionally removed and then treated to form a conductive support via an intermediate layer. Above (this theory) photoreceptor, j: Take anthracene, Anne 1 to Ron, poly-N
- A photoconductive IA material made of vinyl carbazole is optionally included in a binder resin, and a photosensitive layer is optionally incorporated into the photoconductive layer through an intermediate layer made of a water-soluble polymer compound. A photoreceptor is used, which is placed on a power-equalized support. The entire surface of the photosensitive layer is charged by corona discharge using a charger, and then imagewise exposed to light, etc. alms,
An electrostatic latent image is formed on the surface of the photosensitive layer. Next, this electrostatic latent image is developed, for example, by a magnetic brush method, using the developer according to the present invention, to form a 1-toner image. This toner image is, for example, Coronal 9. It is transferred to the transfer body under electric current or transferred to the transfer body by sticky transfer. The toner image transferred to this transfer body can be produced using, for example, a hot plate fixing method, a hot roll fixing method, a pressure saw fixing method,
The image is transferred onto a transfer body using the flash fixation method. The same treatment can be applied to the case where a latent image for electrostatic recording is created without using electrophotography.
