    摘要： 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.

    摘要： An image forming method which includes the steps of providing a developing agent holder for holding one component developing agent layer arranged to contact a latent image holder, developing a latent image on the latent image holder and to simultaneously clean up the developing agent adhering to the surface a non-latent image area on the latent image holder, wherein the cleaning up is carried out under the condition expressed by the following formula:0.5.ltoreq.(Vd/Vp).multidot.m.ltoreq.3.0wherein ghe moving speed of the developing agent holder is defined as Vd, the moving speed of the surface of the latent image holder is defined as Vp and the developing agent adhering density is defined as m (mg/cm.sup.2), and the amount of the remaining toner after transferring that remains on the latent image phase of the latent image holder is set less than 0.35 mg/cm.sup.2. Further, an image forming device is provided with a blade arranged to be pressed against the latent image holder in order to uniformly distribute the toner remaining on the latent image phase of the latent image holder. Therefore, a satisfactory image having excellent quality without ghost images and fogging can be always obtained, and the satisfactory image can be obtained in a high humidity environment.
