Abstract
A developing cartridge includes: a developer carrier which carries toner; a toner supply member which supplies the toner to the developer carrier; a regulation member which regulates an amount of toner on the developer carrier; a developing chamber which has the developer carrier and the toner supply member; a transport section which is connected to an upper portion and a lower portion of the developing chamber and transports the toner from the lower portion of the developing chamber to the upper portion of the developing chamber; and a transport member which is disposed inside the transport section and transports the toner while agitating the toner. A capacity of the transport section is larger than a capacity of the developing chamber.
