Disclosed is a toner for electrostatic image development that has low-temperature fixability and hot offset resistance and also has document offset resistance. The toner contains a hyperbranched polymer which is a homopolymer formed using an inimer having, in its molecule, a polymerizable functional group and a polymerization initiating group or is a copolymer formed using the inimer and a vinyl-based monomer. The hyperbranched polymer is preferably a terminal-modified hyperbranched polymer and is preferably obtained by a living radical polymerization process.

Disclosed is a toner for electrostatic linage development that has sufficient low-temperature fixability, can provide high post-fixing separability, and can be used for stable formation of images at high speed.The toner for electrostatic image development includes toner particles containing a binder resin. The binder resin contains as a part thereof a block copolymer having an A-B-A block copolymer structure including polymer blocks A composed of a structural unit derived from an alkyl methacrylate and a polymer block B composed of a structural unit derived from an alkyl acrylate. The glass transition point (TgA) of a homopolymer of the alkyl methacrylate forming the polymer blocks A is higher than the glass transition point (TgB) of a homopolymer of the alkyl acrylate forming the polymer block B.

摘要:
The present invention provides an exhaust emission purifying apparatus having a liquid level measuring device in which, when a liquid level (measured liquid level) measured by a liquid level indicator of a sensor is equal to or than a measurable lower limit, the measured liquid level is output. On the other hand, when the measured liquid level is less than the measurable lower limit, the liquid level estimated based on a consumption of a liquid reducing agent or its precursor in a reducing agent tank and a tank cross-sectional area is output. The liquid level of the liquid reducing agent or its precursor is estimated in a range in which the liquid level may not be accurately measured due to the presence of a concentration meter, whereby the liquid level can be measured over a wide range.
摘要:
An issue to be settled by the present invention is to define a simulation model in accordance with the structure of a casual relation easy to be understood by human and to shorten greatly a simulation program development period. A simulation program is automatically generated by extracting, as nodes, specific items such as phenomenon, events and targets of constituent elements of economy, society or the like regarded as a system, coupling the nodes with arcs to define the structure of the casual relation, and defining a variable necessary for calculating metrics and a calculation formula therefor, relative to a simulation model inheriting the defined structure.
