摘要:
In electrophotographic process and apparatus of this invention, a drum-like photosensitive member and an endless toner-image bearing member are used. The bearing member is brought into close contact at a part thereof with the sensitive member. The sensitive member is electrically charged. After the bearing member is brought into close contact with the sensitive member, a latent image is formed on the sensitive member. The latent image is developed from an outer side of the bearing member so that a toner image is formed on its surface. To perform ordinary printing, the toner image is transferred onto a support member and then fixed. To conduct printing of multiple copies by using a master, the toner image on the bearing member is fused first to form a master, followed successively by electrical charging of the sensitive member, close contact of the master with the sensitive member, and whole-surface exposure from an outer side of the master. A latent image is formed on the sensitive member. Development of the latent image forms a toner image on the master, which is transferred onto a support member and then fixed.
