| titleOfInvention | Development device, and electrophotographic image formation device |
| abstract | Provided are a development device in which it is possible to reduce the occurrence of fogging in a low temperature environment, and an electrophotographic image formation device with which it is possible to stably form an image over a long period of time. The development device has a toner (1), a development roller (2), and a toner restriction member. The toner (1) satisfies the following conditions: 40≤Z(25)≤80 and 10≤Z(10)≤55 (wherein Z(Y) represents the percentile of (X 3(Y) -X 4(Y) ) relative to X 3(Y) at Y°C, X 3(Y) represents the displacement amount obtained after displacement amount (X 2(Y) ) is left to stand for 0.1 seconds, X 2(Y) represents the displacement amount when a 2.94×10 -4 N load is applied at 9.8×10 -5 N/sec, and X 4(Y) represents the displacement amount at 0N when the load is reduced by 9.8×10 -5 N/sec); 0.49×10 -3 ≤R(25)≤1.70×10 -3 (wherein R(25) represents the tilt from the starting point to the maximum load in the load displacement curve of the toner at 25°C); and 15°C≤(P1-TgA)≤70°C (wherein TgA represents a glass transition temperature between 40 and 60°C, and P1 represents the maximum heat absorption peak temperature between 70 and 110°C). The development roller (2) has a surface layer containing a urethane resin, wherein the urethane resin has at least one of the structures selected from among (a), and (b) and (c). n n -CH 2 -CH 2 -CH 2 -CH 2 -O- Structural formula (a) |
