| titleOfInvention | Developing unit, and electrophotographic image forming apparatus |
| abstract | A developing device capable of reducing the occurrence of fogging and an electrophotographic image forming apparatus capable of forming an image over a long period of time. The developing apparatus includes at least a toner 1 and a developing roller 2. [ (1) Y ℃ from 9.8 × 10 -5 N / sec to 2.94 × 10 -4 N load was added to the obtained amount of displacement d of the displacement X 2 (Y) when, and to the toner left to stand for 0.1 seconds to reach X 3 (Y), and d, 9.8 × 10 -5 N / sec and to reduce the load, the amount of displacement of when the 0N X 4 (Y) of La and, (X 3 (Y) -X 4 (Y)) X Z (25)? 80 and 10? Z (50)? 55 are satisfied when the percentage of 3 (Y) is Z (Y). When the slope of the origin to the maximum load is R (25) in the load displacement curve at 25 占 폚, 0.49 占 10-3? R (25)? 1.70 占 10-3 is satisfied; When the glass transition temperature TgA of the toner is 40 占 폚 to 60 占 폚 and the maximum endothermic peak temperature P1 is 70 占 폚 to 110 占 폚, 15 占 폚 (P1-TgA)? 70 占 폚 is satisfied. (2) The developing roller includes a surface layer containing a urethane resin, and the urethane resin has a structure of Formula (1) and a structure of one or both of Formula (2) to (3). [Chemical Formula 1] (2) (3) |
