The non-magnetic one-component type toner may positively charged non-magnetic one-component type toner at least containing resin and a coloring agent, the resin satisfying the following requirements: the glass transition point is over 50.degree. C.; the softening point is within the range of 110.degree. C.-160.degree. C.; and the frictional charge amount relative to the surface area is within the range of 25.about.150 .mu.C/m.sup.2. The non-magnetic one-component type toner may be prepared by treating the surface of toner containing binder resin whose glass transition point is over 50.degree. C., and whose softening point is within the range of 110.degree..about.160.degree. C., and a coloring agent with a silane coupling agent having an amino group.According to the above method, development fog and the scattering of the toner are prevented so that a visible image of good quality can be formed.

    摘要: A developing apparatus comprises a developing roll for carrying a nonmagnetic toner thereon, and an elastic blade pressed against the outer circumferential surface of the developing roll to apply the toner thereto. The toner is applied to the surface of the developing roll by the elastic blade to form a thin layer of the toner on the surface of the developing roll. The thin layer is opposed to a photosensitive body to deposit the toner on a latent image on the photosensitive body. The developing roll has a surface which is opposite to the photosensitive body and the whole of which is roughened.

    摘要: In a developing device for supplying developer to latent images formed on an image support, a container in which the developer is contained has a sloping bottom. The container has an opening in its top so as to release the developer particles therethrough. The container houses a developer carrier, which is arranged above the sloping bottom of the container with one end located on the lower side of the sloping bottom of the container immersed in the developer particles, and with its other end located on the higher side of the sloping bottom thereof. The developer carrier has a plurality of linear electrodes arranged thereon, starting from one end to the other end, and has an electric field generator connected to these linear electrodes to successively apply voltages to these electrodes so as to generate an electric field which advances according to a lapse of time, whereby the developer particles are carried along the developer carrier, from one end to the other. That part of the developer particles which does not contribute to the developing of the image is also carried from near the opening to the other end, where it slides down by its own weight on the sloping bottom of the container to return to and near the one end again.
