Abstract

PURPOSE: To ensure a steady transport of the developer without dropping the developer even in case when the developer may be stayed at the developing part, by controlling the width of path of the development at both the inlet and outlet sides of the developing region to the development nip.
CONSTITUTION: The developer which is transported to the developing part is controlled to a certain thickness when it passes through the gap between the sleeve 2 of the development roll 1 and the trimming component 8. This gap is set a little wider than the space between the sleeve 2 and the photoreceptor 4. Accordingly, slight an exessive amount of the developer 5 is supplied to the development nip to form the stay part 6 of a fixed amount of developer at the side where the developer flows in. To prevent this stay of the developer from extending toward the shaft of the roll 1 and then dropping off through both ends, the width of the development transport path at the inlet side of the developing region is set identical to the length of the magnet 3 of the roll 1. At the same time, the width of the development transport path at the outlet side of the developing region is set larger than the length of the magnet.
