Abstract

PURPOSE: To reduce the contamination of an image by bringing a cleaning means which has left during its suspension into contact with the surface of a rotary body to which liquid is given before the formation of a latent image, or by operating the cleaning means after a predetermined time since a developing means which gives the liquid is operated.
CONSTITUTION: In the step A before practicing copy, the electric power is made ON to rotate photoreceptor 1 only with developing roller 9 and cleaning blade 10 in the non-contact state. In the step B, the developing roller 9 only is brought into contact with the photoreceptor 1, and the photoreceptor 1 is rotated to humidify its whole surface. In the step C, the cleaning blade 10 is brought into contact with the photoreceptor 1 to completely clean the whole surface of the photoreceptor 1, and copying is done by making the copy button ON. In the step D, the photoreceptor 1 is rotated to completely clean its whole surface with the developing roller 9 while the roller 9 is in contact therewith, but the blade 10 is out of contact. At this time the photoreceptor 1 is put at the non-development potential. In the step E, the photoreceptor 1 is suspended with the roller 9 and bload 10 out of contact with the photoreceptor 1.
