  • Magnetic Brush Developing In Electrophotography (AREA)

Abstract

PURPOSE: To reduce unevenness in development by carrying out development at two or more points and relatively changing the developer moving speed at the points.
CONSTITUTION: Sleeves 2, 3 are parallelly placed by the side of recording member 1, and development is carried out with one developing magnetic pole each of sleeves 2, 3. A developer is retained by setting the magnetic pole of sleeve 2 downward from a line connecting the centers of member 1 and sleeve 2, and this angle α is adjusted to 5W20°. Thus, unevenness in development is reduced, and development of high density is performed.
