摘要:
In an imaging color toner employing a photofixing system, a binder resin, which contains, as a principal component, a polyester resin obtained by mixing a first polyester resin having a softening point Tsp of not lower than 120° C. and lower than 170° C. with a second polyester resin having a softening point Tsp of not lower than 80° C. and lower than 110° C. in a weight ratio of 80:20 to 20:80, is used. The color toner is used in an electrophotographic process and other imaging processes.

The present invention provides a toner for developing an electrostatic latent image comprising a releasing agent containing a hydrocarbon, a binder resin, and a colorant, wherein, when an average carbon number of the hydrocarbon is designated as N, the hydrocarbon contains components having a carbon number in the range of (N−10) to (N+10) in an amount of 70% by mass or more in the entire hydrocarbon and has a weight-average molecular weight of 12,000 or more and 25,000 or less, a developer for developing an electrostatic latent image containing the toner for developing an electrostatic latent image, and an image-forming process using the toner for developing an electrostatic latent image.
摘要:
A developing device for electrophotographic image has a developing mechanism having a developer carrier for carrying a developer along a preset circulating route including a developing area and a developer restricting element for restricting the developer on the developer carrier, and a developer supply mechanism having a storing unit. The storing unit is filled with a start-up developer in the vicinity of the developer carrier and a replenishing developer remoter than the start-up developer from the developer carrier. The start-up developer and the replenishing developer have different grain sizes or grain size distributions. Further, a developing method for electrophotograhic image has the steps of using the start-up developer at an initial state of use of the developing mechanism, and using the replenishing developer differed in grain size or grain size distribution from the start-up developer after an end of the initial state of use of the developing mechanism.

A method of optimizing fuel economy and carbon dioxide emissions of a vehicle may entail utilizing an interior vehicle display to alert a driver as to the state of various vehicle components and parameters and their effect on fuel economy and carbon dioxide emissions. The components and parameters may be monitored by or direct information into a vehicle efficiency ECU which communicates with the display. The method may entail reading and displaying a real-time tire pressure into the efficiency ECU and displaying the corresponding fuel economy. a manufacturer's recommended tire pressure and corresponding fuel economy could also be displayed. The method may also entail reading a variety of real-time weather conditions into the efficiency ECU that correspond to a plurality of different road routes to a driver-selected destination. The fuel economy of each route may be displayed for driver selection to optimize fuel economy and carbon dioxide emissions.

Using a remote control, a viewer specifies the channel and the date and time of a program that he/she wants to watch. A reception method selection unit determines, based on the date and time, whether the program is currently being broadcast or was broadcast in the past, and then selects a reception method. An SI information storage unit stores URL information of program distribution servers having past programs. The URL information is contained in the SDT in SI information transmitted together with a program. When the viewer chooses a past program, an IP data reception unit connects to the corresponding program distribution server based on its URL so as to transmit the date and time thereto, and receives the past program that the viewer wants to watch via IP network.
