Image forming machine with a contact type developing device |
摘要 |
An image forming machine including a single layer dispersion type photoconductor drum, a charging device for charging the surface of the photoconductor drum to a specific polarity, and a developing roller for conveying a developer to the surface of the photoconductor drum having a latent electrostatic image formed thereon. The photoconductor drum and the developing roller are adapted to contact each other at their surfaces and to be rotationally driven in reverse directions. The photoconductor drum has a diameter set at 10 to 20 mm, while the developing roller has a diameter set at 90 to 110% of the diameter of the photoconductor drum.
