    • This invention relates to a cleanerless developing method using a mono-component toner, which method effects simultaneous developing and cleaning operations in the step of development. It more particularly relates to a method which is capable of forming images of outstanding quality without entailing generation of positive memory or negative memory. In the cleanerless developing method using a mono-component toner, the absolute value of the magnitude, .vertline.q.sub.t .vertline., of charging the developing toner to be used is selected to fall in the range between 0.5 [mC/kg] and 40 [mC/kg], the absolute value of the magnitude, .vertline.q.sub.r .vertline., of charging the residual toner to be introduced into the step for simultaneous developing and cleaning as deposited on the surface of the latent image retaining member is set to fall in the range between 0.5 [mC/kg] and 60 [mC/kg], or the absolute value of the magnitude, .vertline.q.sub.z .vertline., of charging the residual toner during the step for uniformizing the residual toner is selected to fall below the upper limit of 40 [mC/kg]. By selecting the magnitude of charging the toner within at least one of the ranges mentioned above, the cleanerless developing method using a mono-component toner is always and easily enabled to produce images of high quality without entailing the generation of positive memory or negative memory.

    • 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.
