A photoconductor is disclosed, which comprises a conductive cylindrical support which is substantially not hollowed, the conductive cylindrical support having a drive transferring mechanism coaxially and unifiedly provided on at least one of the end portions thereof, the conductive cylindrical support having a photoconductive layer on the outer periphery. The moment of inertia I (g . cm.sup.2) of the substantially not-hollowed conductive support is in the range of 0.4.ltoreq.I.ltoreq.140 (g . cm.sub.2), the diameter thereof being in the range from 0.5 to 2.0 cm. When the relation of C/(S . .omega.).ltoreq.0.4 (where S (cm.sup.2) is the square measure of the portion of the photoconductive layer on the photoconductor; C (cal/.degree.C.) is the heat capacity of the substantially not-hollowed cylindrical support; and .omega. (rad/s) is the rotating speed in development) is satisfied, high quality images can be readily and stably obtained without damages of the drive system.

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.
