Problems solved by technology
Therefore, if the developer cartridge is miniaturized, the angle of rotation for opening and closing the shutter becomes large, making it difficult to ensure the passage of the shutter
Therefore, there arises a problem that the opening area of the opening portion must be reduced

A developer cartridge detachably mounted to a device main body includes a tubular cartridge main body that houses a developer and an extending portion that communicates with the cartridge main body, which extends from an end portion in a longitudinal direction of the cartridge main body. An outside shape of a section of the extending portion, along a direction that is orthogonal to the longitudinal direction, is smaller than that of the cartridge main body. A cartridge-side opening portion is provided at a side wall of the extending portion, and a cartridge-side shutter is provided at an outside of the side wall of the extending portion, which moves in a direction intersecting the longitudinal direction along the side wall to thereby open and close the cartridge-side opening portion.
Description
Developer cartridge and image forming unit technical field The invention provides a developer cartridge and an image forming device. Background technique In an image forming apparatus, developer is supplied from a developer cartridge to a developing unit. When the developer in the developer cartridge runs out, the developer cartridge is detached from the image forming apparatus, and replaced with a new developer cartridge. As such a type of developer cartridge, there is a long cylindrical developer cartridge having an opening portion formed in a side wall to supply the developer to the developing unit, and a shutter for opening and closing the opening portion (For example, see Japanese Patent Application Laid-Open No. 2001-83792). In order to miniaturize the developer cartridge, even if the outer shape of the cross-section perpendicular to the longitudinal direction is miniaturized, it is necessary to ensure the opening area of the opening portion so that the develop...
