Developing apparatus, process cartridge, and image forming apparatus

A developing apparatus containing a developer including a toner and a carrier and configured to develop a latent image formed on an image carrier,

• the developing apparatus comprising:
• a developer carrier including plural magnetic poles and disposed opposite to the image carrier;
• a developer regulating member configured to regulate an amount of the developer carried by the developer carrier;
• and
• a developer circulating unit configured to transport the developer in a horizontal direction in a circulating path;
• wherein an edge of the developer regulating member is disposed opposite to a lower part of the developer carrier,
• the developer circulating unit includes a rotatable first transport member configured to supply the developer to the developer carrier while transporting the developer in the horizontal direction, a shielding member configured to prevent the developer separated from the developer carrier from flowing back toward the first transport member, and a rotatable second transport member configured to collect the developer separated from the developer carrier and transport the developer in the horizontal direction,
• wherein the second transport member is spaced apart from the developer carrier by a distance greater than a distance between the developer carrier and the first transport member.
