Toner layer thickness regulation member and image forming apparatus having same
There is provided according to the present invention a toner layer thickness regulation member capable of suppressing uneven density during forming an image. There is also provided an image forming apparatus capable of forming an excellent image stably by employing such a toner layer thickness regulation member. A toner layer thickness regulation member 1 has a strip metal plate 2 and an elastic member 3 provided in one side of the metal plate 2 in a width direction and arranged in parallel to a longitudinal direction of the metal plate, wherein the elastic member 3 has hardness of more than 55° and hardness relaxation of less than 2.6°. In addition, an image forming apparatus employs the above-mentioned toner layer thickness regulation member 1.

a strip metal plate; and
an elastic member provided in one side of the metal plate in a width direction and arranged in parallel to a longitudinal direction of the metal plate,
wherein the elastic member has hardness of more than 55° and hardness relaxation of less than 2.60.
2. The toner layer thickness regulation member according to claim 1 , wherein the elastic member has hardness of more than 70°.
3. The toner layer thickness regulation member according to claim 1 , wherein the elastic member has hardness of more than 65° and hardness relaxation of less than 2.0°.
4. The toner layer thickness regulation member according to claim 1 , wherein the elastic member has hardness of more than 55° and hardness relaxation of less than 1.2°.
5. The toner layer thickness regulation member according to claim 1 , wherein the elastic member has hardness of less than 85.
6. An image forming apparatus, wherein the toner layer thickness regulation member according to claim 1 is used.
