                        the binder resin contains, as a principal component, a polyester resin                         
                 obtained by mixing a first polyester resin with a second polyester resin in a                         
                 weight ratio of 80:20 to 20:80;                                                                       
                        the fist polyester resin is a crosslinked polyester resin having a                             
                 softening point Tsp of not lower than 120ºC and lower than 170ºC, and also                            
                 contains 1 to 25 parts by weight of a chloroform-insoluble content as the                             
                 component; and                                                                                        
                        the second polyester resin is a non-crosslinked polyester resin having                         
                 a softening point Tsp of not lower than 80ºC and lower than 110ºC, wherein                            
                 the toner is capable of being photofixed; and                                                         
                        wherein an acid value of the first polyester resin is from 20 to 40, an                        
                 acid value of the second polyester resin is from 5 to 20, and an acid value of                        
                 the entire polyester resin is from 15 to 35.                                                          
                        19.  An imaging color toner comprising at least a binder resin, a                              
                 colorant and an infrared absorber, wherein;                                                           
                        the binder resin contains, as a principal component, a polyester resin                         
                 obtained by mixing a first polyester resin with a second polyester resin in a                         
                 weight ratio of 80:20 to 20:80;                                                                       
                        the first polyester resin is a crosslinked polyester resin having a                            
                 softening point Tsp of not lower than 120ºC and lower than 170ºC, and also                            
                 contains 1 to 25 parts by weight of a chloroform-insoluble content as the

                        the second polyester resin is a non-crosslinked polyester resin having                         
                 a softening point Tsp of 110ºC, wherein the toner is capable of being                                 
                 photofixed; and
