Abstract
Provided is a toner that achieves low-temperature fixability, storability and charging performance all at a high level, in which a toner containing a crystalline resin and an amorphous resin, wherein a standard deviation of hydrogen nuclear relaxation times (HT1ρ-C) of the toner as measured by solid-state 13C-NMR is from 0.0 to 5.0, and a hydrogen nuclear relaxation time (HT1ρ-C1) of a 13C peak with the longest relaxation time out of the hydrogen nuclear relaxation times (HT1ρ-C) and a hydrogen nuclear relaxation time (HT1ρ-A1) of a 13C peak with the shortest relaxation time out of the hydrogen nuclear relaxation times (HT1ρ-A) satisfy 3.0≦{(HT1ρ-C1)/(HT1ρ-A1)}≦6.0.
