  • Publication number: 20240097441
    Abstract: A management system includes a plurality of resources configured to be electrically connected to an external power supply, and a management device configured to manage the resources. The management device includes a planning unit and a management unit. The planning unit is configured to determine a power balancing plan of each of the resources by using first information on a use schedule of each of the resources and second information indicating a magnitude of an environmental load in a process of generating electric power to be supplied by the external power supply. The management unit is configured to manage the resources to cause each of the resources to operate according to the power balancing plan or a modified power balancing plan in power balancing of the external power supply.

  • Publication number: 20230418181
    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.
