Abstract

An image forming apparatus includes a transfer member, a fixing member, a guide member, and an attraction member. The transfer member transfers a developer to a medium. The fixing member fixes onto the medium the developer transferred to the medium. The guide member is disposed between the transfer member and the fixing member to guide the medium. The attraction member attracts the developer through the opening. An opening is located upstream of the guide member in a medium transport direction.

Claims (17)

1. An image forming apparatus, comprising:

a transfer member that transfers a developer to a medium;

a fixing member that fixes onto the medium the developer transferred to the medium;

a guide member that is disposed between the transfer member and the fixing member to contact and guide the medium, the guide member being a stationary member;

an attraction member that attracts the developer through an opening;

an elimination member that allows gas to pass therethrough while removing the developer attracted through the opening, the elimination member being removable from and attachable to a body of the image forming apparatus; and

an open-close member that is supported to be openable and closeable between an open position, in which the open-close member renders an inside of the image forming apparatus open, and a closed position, in which the open-close member renders the inside of the image forming apparatus closed, the open-close member supporting the elimination member, the open-close member allowing, when in the open position, an upstream surface of the elimination member in a direction in which the developer is attracted to face upward with respect to a direction of gravity,

wherein the opening is located upstream of the guide member in a medium transport direction, on a same side of the medium as the guide member, and is stationary with respect to a transfer location where the transfer member transfers the image to the medium,

wherein the opening is located in an upstream half of a path between the transfer member and the fixing member.

2. The image forming apparatus according to claim 1 , further comprising:

a positioning member disposed on the body of the image forming apparatus; and

a to-be-positioned member disposed on the elimination member, the to-be-positioned member coming into contact with and being fixed to the positioning member when the elimination member is attached to the body of the image forming apparatus.

3. The image forming apparatus according to claim 1 ,

wherein the elimination member is attached to and removed from the body of the image forming apparatus by moving toward and away from the open-close member while the upstream surface of the elimination member faces upward.

4. The image forming apparatus according to claim 1 , further comprising:

a flow-path forming member that is disposed upstream of the attraction member in a direction in which the developer is attracted to form a path through which gas is transported, the flow-path forming member being fixed to and supported by a body of the image forming apparatus,

wherein the attraction member is supported by the body of the image forming apparatus by being held between the flow-path forming member and a frame of the image forming apparatus.
