Abstract: A hybrid fiber which includes: a metal wire having a roughened surface; and a fiber is provided. In the hybrid fiber, the metal wire and the fiber are combined.

Abstract: An image forming apparatus includes lock mechanisms, a regulation processing portion, and a second release processing portion. The lock mechanisms correspond to attachment portions to each of which a developer storage portion is attached, and each regulate detachment of a developer storage portion attached to an attachment portion. When a first state where developer storage portions of a specific type are attached to all the attachment portions, has been detected, and there is a lock mechanism that is not regulating detachment, the regulation processing portion causes the lock mechanism to regulate detachment of the developer storage portion. When a second state where a developer storage portion of the specific type has not been attached to at least one attachment portion, has been detected, and all the lock mechanisms are regulating detachment, the second release processing portion causes all the lock mechanisms to release regulation of detachment.

Abstract: A radioprotective unwoven fabric is a sheet in which metal fibers are three-dimensionally and randomly stacked, the metal fibers each comprising a metal material having a specific gravity higher than a specific gravity of lead. The metal fibers may comprise a tungsten wire.

Abstract: An image forming apparatus includes a mounting portion, a lock mechanism, an image forming unit, a first detection processing unit, a second detection processing unit, a first release processing unit, and a second release processing unit. The first detection processing unit detects a first state where a remaining amount of the developer is less than a predetermined first reference amount. The second detection processing unit detects a second state where the remaining amount of the developer is equal to or more than the first reference amount and less than a predetermined second reference amount. The second reference amount is larger than the first reference amount. The first release processing unit releases the regulation on the attachment/removal of the developer housing portion when the first state is detected. The second release processing unit releases the regulation when unit the second state is detected and a predetermined release condition is met.

Abstract: An image forming apparatus includes a lock mechanism, a first determination processing portion, and a regulation processing portion. The lock mechanism is configured to regulate attachment and detachment of the developer storage portion attached to the attachment portion. The first determination processing portion determines whether or not the developer storage portion attached to the attachment portion is a developer storage portion of a predetermined specific type. The regulation processing portion, when the developer storage portion attached to the attachment portion has been determined to be a developer storage portion of the specific type, causes the lock mechanism to regulate attachment and detachment of the developer storage portion.

Abstract: An image forming apparatus includes lock mechanisms, a second detection processing portion, and a second release processing portion. The lock mechanisms regulate attachment and detachment of the developer storage portions attached to the attachment portions. The second detection processing portion detects whether or not any of the image forming units has an abnormality. The second release processing portion can release a regulation on attachment and detachment of two or more developer storage portions corresponding to two or more image forming units that include at least an image forming unit adjacent to the image forming unit detected to have the abnormality.

Abstract: A fluorescent lamp is configured so that a glass bulb has a phosphor film formed on its internal face, and a rare gas and an amalgam pellet are enclosed therein. The amalgam pellet contains zinc, tin, and mercury as principal components, one amalgam pellet is enclosed in the glass bulb, and the amalgam pellet has a weight of not more than 20 mg. The fluorescent lamp satisfies the relationship expressed as: 45×(1?A)?x?55×(1?A), 75A?y?85A, 45?30A?z?55?30A, and x+y+z?100, where x represents a content of zinc contained in the amalgam pellet in percent by weight, y represents a content of tin therein in percent by weight, and z represents a content of mercury therein in percent by weight. This configuration allows the fluorescent lamp to be characterized in that an amount of released mercury that is necessary for the first lighting of the fluorescent lamp is secured, and that the phosphor film is less prone to being peeled due to the amalgam.
