Document Type and Number:
Japanese Patent JP4185927
Kind Code:
B2
Abstract:
A developing device includes: a developing roller; a magnet provided in the roller and having a plurality of local maximum magnetic flux density positions on the peripheral surface of the magnet; a developing container supporting the roller; a seal member for preventing a developer from leaking out of the container; and a developer regulating member having a scraping member abutting the roller for collecting the developer on the surface of the roller toward the inside of the container in the axial direction. When viewing the developing device in the axial direction, the scraping member abuts the roller between a first position where the surface of the roller is crossed by a line which connects the supporting portion and a local maximum magnetic flux density position that is nearest to the supporting portion, and a second position where the roller develops the latent image.
