Abstract (en)
In a conventional electrophotographic printing machine, a cleaning device which has been used to remove residual toner is eliminated by using a toner and a carrier each having a spherical configuration so as to cause a cleaning operation and a developing operation to proceed simultaneously at the developing unit. With this printing machine not only the construction of the machine can be simplified but also an extremely fine toner can be efficiently used.
