Fixing device and image forming apparatus
View Patent ↗A fixing device includes a rotatable pressure member; a heating member that is provided so as to oppose the pressure member, and that includes a heat source; a fixing member that fixes an image to a recording medium as a result of transporting the recording medium while the recording medium is nipped at a nip when the fixing member is pressed by the pressure member, the image being formed of toner including a separating agent; a cooling unit that cools the pressure member at a location that is situated downstream of the nip; a removing roller that, while being driven and rotated by the pressure member, removes the separating agent from the pressure member, the separating agent being transferred from the fixing member; and a removing member that contacts the removing roller and removes the separating agent adhered to the removing roller from the removing roller.
1. A fixing device comprising:
a rotatable pressure member;
a heating member that is provided so as to oppose the pressure member, the heating member including a heat source;
a fixing member that is contacted by the heating member, the fixing member fixing an image to a recording medium as a result of transporting the recording medium while the recording medium is nipped at a nip when the fixing member is pressed by the pressure member, the image being formed of toner including a separating agent, the nip being formed between the fixing member and the pressure member;
a cooling unit that cools the pressure member;
a removing roller that, while being driven and rotated by the pressure member, removes the separating agent from the pressure member, the separating agent being transferred from the fixing member; and
a removing member that contacts the removing roller and removes the separating agent adhered to the removing roller from the removing roller,
wherein the cooling unit cools the pressure member at a location that is different from where the removing roller contacts the pressure member,
wherein the removing roller is provided upstream of the nip in a direction of rotation of the pressure member and downstream of the cooling unit in the direction of rotation of the pressure member.
2. The fixing device according to claim 1 , wherein the removing member is formed of a fiber member that contacts the removing roller while the removing member moves.
3. An image forming apparatus comprising:
an image holding member on which an electrostatic latent image is formed;
a developing device that develops with toner including a separating agent the electrostatic latent image formed on the image holding member;
a transfer device that transfers a toner image developed by the developing device to a recording medium; and
the fixing device according to claim 2 that fixes the toner image transferred to the recording medium to the recording medium.
4. An image forming apparatus comprising:
an image holding member on which an electrostatic latent image is formed;
a developing device that develops with toner including a separating agent the electrostatic latent image formed on the image holding member;
a transfer device that transfers a toner image developed by the developing device to a recording medium; and
the fixing device according to claim 1 that fixes the toner image transferred to the recording medium to the recording medium.
5. The fixing device according to claim 1 , wherein the cooling unit cools the pressure member by directly impinging the pressure member surface with cooling air.
