Abstract
This disclosure provides a developer container in which a conductive resin sheet is used as an electrode for detecting an amount of developer by using electrostatic capacitance. A configuration in which an end of the conductive resin sheet in a longitudinal direction is provided outside an end of a sheet member in a longitudinal direction, or a configuration in which the sheet member starts contact with the conductive resin sheet from a second surface on the downstream side in a direction or rotation than a first surface are also provided.
