US 2020/0026220 A1 · DEVELOPER CONTAINER HAVING A CAP WITH THREE PORTIONS OF DIFFERENT DIAMETERS

Abstract

A toner container includes a container body, an opening, a cover, a toner discharge port, a shutter, a cylindrical structure, protrusions, and an identifier. The shutter is attached to the cover and includes a main shutter covering the toner discharge port. The main shutter moves between a closed position to close the toner discharge port and an open position to open the toner discharge port. The protrusions are on both sides of the cover and protrude in a direction orthogonal to a toner container mounting direction. The identifier is on the cover to indicate a toner color. The cylindrical structure's leading end is downstream of leading ends of the protrusions in the mounting direction. The main shutter's leading end is downstream of the protrusions' leading ends in the mounting direction when the main shutter is in the closed position. The protrusions are downstream of the identifier in the mounting direction.

(canceled)

A container for storing developer, comprising:

a cap including:
a developer discharge port for discharging the developer;
a large diameter portion having an inner diameter which is a first size;
a medium diameter portion having an inner diameter which is a second size which is smaller than the first size;
a small diameter portion having an inner diameter which is a third size which is smaller than the second size,
a lateral protrusion on an outer peripheral surface of the small diameter portion, the lateral protrusion including at least a front portion and a rear portion that each protrude in a lateral direction away from the outer peripheral surface of the small diameter portion, the lateral direction being perpendicular to a longitudinal direction of the container, the lateral protrusion protruding further in the lateral direction than an outer radius of the medium diameter portion.
