Title:
DEVELOPMENT METHOD
Document Type and Number:
Japanese Patent JP3274096
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a development method which is capable of electrifying toner to a specific polarity steadily, is suitable for developing the magnetic toner into a high resolution image, and is capable of developing the magnetic toner by pressure-contact.
SOLUTION: In the development method for forming the toner 8 into a thin layer on a toner carrier 9 by means of an elastic blade 13 and developing the toner 8 on the toner carrier 9 to a latent-image carrier 1, the toner 8 is spherical, and rolls and is electrified on the toner carrier 9 by the elastic blade 13, and the toner carrier 9 is in pressure contact with the latent-image carrier 1. Also, the toner carrier 9 has a magnetic-field generation layer 22 on its surface, the toner 8 is magnetic, and the film thickness of the magnetic-substance generation layer is 100 μm or less.
