Abstract: A toner container includes a container body, a cap, bosses and a cover. The container body has a toner filling port. The cap is detachable and closes the filling port. The bosses are provided on the container body. The cover is detachably attached to the container body so as to cover the filling port and the bosses, and has a through hole through which each of the bosses penetrates. The boss has a tip end portion protruding from the cover through the through-hole. The tip end portion is provided so as to regulate detachment of the cover by being worked into a head portion having a cross-sectional area larger than the through-hole, and to permit the detachment of the cover by cutting off the head portion. The container body, the cap and the cover can be reused maximum by the number of times corresponding to the number of the bosses.

Abstract: A developer storage container includes a container body and a shape forming member. The developer storage container is attached to and detached from any one of three or more mounting portions provided to an image forming apparatus forming an image using a developer. The container body has a side wall portion formed in a mounting direction to the image forming apparatus. The shape forming member is attached to the side wall portion in a mode to correspond to any one of three mounting portions, forming a first non-compatible shape corresponding to this mounting portion.

Abstract: A toner storage case includes a case main body, a rotary member, a support shaft portion, a bearing portion, and a toner returning portion. The case main body is configured to store toner therein. The rotary member is provided in the case main body and configured to move the toner by being rotated. The support shaft portion rotatably supports the rotary member. The bearing portion includes a bearing hole that rotatably supports the support shaft portion in a state where the support shaft portion is inserted in the bearing hole. The toner returning portion is provided on an outer peripheral surface of the support shaft portion and configured to return the toner that has entered the bearing hole, in an outward direction toward an outside of the bearing hole as the rotary member is rotated.

Abstract: A solder ball includes 0.1% by mass or more and 10% by mass or less of In and a remainder of Sn. The ball has a yellowness (b*) in an L*a*b* color system of 2.8 or more and 15.0 or less and a lightness (L*) of 60 or more and 100 or less. The ball further includes at least one element selected from a group of 0% by mass or more and 4% by mass or less of Ag, 0% by mass or more and 1.0% by mass or less of Cu, 0% to 3% by mass in total of Bi and/or Sb, and 0% to 0.1% by mass in total of an element selected from a group of Ni, Co, Fe, Ge, and P, excluding a solder ball including 3% by mass of Ag, 0.5% by mass of Cu, 0.2% by mass of In and a remainder of Sn.

Abstract: A device is provided to be able to spray over a wide range and suppress a chilling injury. In the device, a rotating nozzle is connected to a connection pipe having a connection passage in communication to a nozzle stem of an aerosol can to have an outlet directed laterally. The rotating nozzle comprises a hollow support having a connection passage connected to a connection passage outlet of the connection pipe and a hollow arm rotatably supported at a tip end of the support, and an arm orifice is provided at a tip end of a connection passage in the arm and oriented such that reaction force of spray causes the rotating nozzle to rotate and aerosol contents are sprayed forwardly of a rotating plane of the rotating nozzle.
