1. a Thermochromic color Memorability toner, it is at least containing the microcapsules pigment including Thermochromic color Memorability composition, with binding resin, described Thermochromic color Memorability composition comprises (A) to electronics colour rendering organic compound, (B) (A) is controlled by electron compound and (C) conduct, (B) reaction medium of chromogenic reaction such as formula the compound shown in (1), described microcapsules pigment shows large hysteresis characteristic and presents the enantiotropy of color status and bleached state on color density-temperature curve, and show following hysteresis characteristic:

  • in the process that temperature rises under color status, reach temperature t 3in time, starts to fade, higher than temperature t 3temperature t 4fade completely, at temperature t 4become bleached state completely in above temperature province, in the process that temperature declines under bleached state, reach lower than described temperature t 3temperature t 2time start colour developing, lower than temperature t 2temperature t 1develop the color completely, at temperature t 1color status is completely become, at described temperature t in following temperature province 2with temperature t 3between temperature province in visually confirm a kind of state be selected from color status or bleached state, wherein, temperature t 1in the scope of-50 ~ 0 DEG C, temperature t 4in the scope of 70 ~ 150 DEG C,
