Abstract
A developing device in an apparatus main body of an image forming device includes a developing container having an accommodation chamber to accommodate a developer and a developing chamber communicating with the accommodation chamber through a communication port, with the accommodation chamber and developing chamber being integrally formed such that the developing chamber is disposed below the accommodation chamber in a state where the developing device is in use in the apparatus main body. The developer container includes an abutting surface which forms the accommodation chamber and abuts a second end portion of a sheet opposite to a first end portion such that the sheet is maintained in a bent state until the second end portion of the sheet passes in front of an upstream end of the communication port in a rotation direction of the conveyance member and then reaches a light guide provided in the accommodation chamber.
