摘要： Disclosed is a decolorable toner produced by aggregating dispersed fine particles of a color material containing at least a color-forming compound, a color-developing agent and a decoloring agent with dispersed fine particles containing at least a binder resin having a carboxyl group, then adding a compound having a carbodiimide group or an epoxy group reactive with the carboxyl group of the binder resin, and thereafter fusing the aggregate particles, respectively in an aqueous medium. The thus obtained decolorable toner can suppress the generation of fine powder by the release of erasable color material fine particles from the toner particles.

摘要： A portable communication terminal which can establish communications between portable communication terminals by Bluetooth or the like by a simple operation are provided. An initiator terminal activates a short-distance radio communication section to make a Bluetooth function active and sends a request to start communications using a Bluetooth communication function to an acceptor terminal through a general communications network such as a telephone network or the like. The acceptor terminal makes the Bluetooth communication function active when it responds to the communication-starting request and sends a Bluetooth connection request to the initiator terminal by using the Bluetooth communication function. The initiator terminal responds to the Bluetooth connection request whereby a Bluetooth connecting session is established.

摘要： Disclosed is a toner obtained by coating surfaces of core particles including at least a binder resin having a carboxyl group and a coloring agent with successive coatings of a water-soluble crosslinking agent capable of crosslinking with a carboxyl group and a water-soluble polymer having a carboxyl group, which have been successively applied on the core particles and crosslinked with each other. The thus-formed toner is provided with a good harmony of favorable fixability represented by a low lowest fixable temperature and favorable storage stability represented by little aggregation after standing at 50° C. for 8 hours.
