Abstract: In a soot blower, a heat transfer tube of a heat exchanger is arranged inside a pressure vessel, and gas for cleaning is injected toward the heat transfer tube from an injection pipe movable into and out of the pressure vessel. The soot blower includes a cylindrical casing provided to surround an insertion hole on the pressure vessel side into which the injection pipe is inserted, to extend outside the pressure vessel, the injection pipe being inserted into an inside of the casing; a support part provided inside the casing to guide movement of the injection pipe and to ensure airtightness between the casing and the injection pipe; and a gas supplying device provided immediately close to the support part to generate a jet stream of gas in a portion of the injection pipe that projects to the pressure vessel side.

Abstract: An image forming apparatus includes a first toner image forming unit, a second toner image forming unit, and a transfer section. The first toner image forming unit forms a first toner image with use of a first toner. The first toner has a complex viscosity that falls within a range from 625 Pascal-seconds to 3860 Pascal-seconds, both inclusive, at a temperature of 100 degrees centigrade. The second toner image forming unit forms a second toner image with use of a second toner. The transfer section transfers the first toner image onto a print medium, and transfers the second toner image onto the print medium in a region that overlaps a portion or all of a region where the first toner image has been transferred. The print medium includes a polymer compound.

Abstract: An image forming apparatus includes a first toner image forming unit, a second toner image forming unit, and a transfer section. The first toner image forming unit forms a first toner image with use of a first toner. The first toner includes a binder resin. The binder resin has a weight-average molecular weight that falls within a range of from 12297 to 14019, both inclusive. The second toner image forming unit forms a second toner image with use of a second toner. The transfer section transfers the first toner image onto a print medium, and transfers the second toner image onto the print medium in a region that overlaps a portion or all of a region where the first toner image has been transferred. The print medium includes a polymer compound.

Abstract: A toner includes an external additive particle that is a complex oxide containing a titanium dioxide (TiO2) and a silicon dioxide (SiO2). A detection amount of titanium (Ti) detected through an elementary analysis based on energy-dispersive X-ray spectrometry is equal to or higher than about 0.590 percent by weight and equal to or lower than about 0.967 percent by weight.
