Image forming apparatus including guide and attracting members

1. An image forming apparatus comprising:

a guide member located downstream of a transfer section, the guide member guiding a print medium that carries a developer image thereon, the print medium being transported in a transport path; and

an attracting member extending in a direction parallel to the transport path, and disposed at a position where when the print medium is guided by the guide member, the attracting member attracts the print medium toward the attracting member such that the guide member is positioned between the print medium and the attracting member, a gap being formed between the attracting member and the print medium to prevent the print medium from directly contacting the attracting member as the print medium passes by the attracting member.

2. The image forming apparatus according to claim 1 , wherein the developer image is negatively charged when the print medium passes through the transfer section, and the attracting member is connected to a ground potential so that the print medium is attracted electrostatically by the attracting member.

3. The image forming apparatus according to claim 1 , further comprising a neutralizing member that neutralizes a non-image side of the print medium, wherein the attracting member and the neutralizing member are a single piece construction.

4. An image forming apparatus comprising:

a guide member located downstream of a transfer section, the guide member guiding a print medium that carries a developer image thereon, the print medium being transported in a transport path;

an attracting member extending in a direction parallel to the transport path, and disposed at a position where when the print medium is guided by the guide member, the attracting member attracts the print medium toward the attracting member such that the guide member is sandwiched between the print medium and the attracting member;

an environmental condition detector that detects environmental conditions in the image forming apparatus;

a power supply that applies a voltage to the attracting member so that the print medium is attracted electrostatically by the attracting member; and

a controller configured to control the power supply based on the environmental conditions so that the power supply changes the voltage in accordance with the environmental conditions.

5. The image forming apparatus according to claim 4 , wherein the power supply is a first power supply of a plurality of power supplies and the voltage is a first voltage, wherein the image forming apparatus comprises a second power supply that applies a second voltage to the transfer section; and

wherein the controller is configured to control the second power supply based on the environmental conditions so that the second power supply changes the second voltage in accordance with the environmental conditions.

6. The image forming apparatus according to claim 4 , wherein the environmental condition detector is a humidity sensor.

7. The image forming apparatus according to claim 4 , wherein the environmental condition detector is a temperature sensor.

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

a neutralizing member that neutralizes a non-image side of the print medium;

a space defining member that is upstream of the neutralizing member in the transport path and defines a gap between the print medium and the neutralizing member when the print medium is transported in the transport path after passing through the transfer section; and

wherein the attracting member attracts the print medium after the non-image side of the print medium is neutralized by the neutralizing member.

9. The image forming apparatus according to claim 8 , further comprising a support member, wherein the attracting member and the neutralizing member are formed of metal and are supported by the support member.

10. The image forming apparatus according to claim 9 , wherein the guide member, the space defining member, and the support member are a single piece construction.

11. The image forming apparatus according to claim 1 , wherein the gap is disposed between the attracting member and the print medium so that the attracting member is free of any contact with all of the print medium for all the print medium passing by the attracting member.

12. The image forming apparatus according to claim 1 , wherein the attracting member is electrically conductive and is connected to a predetermined potential.

13. The image forming apparatus according to claim 1 , wherein a portion of the attracting member is configured to neutralize charges on the print medium.

14. The image forming apparatus according to claim 13 , further comprising a neutralizing member located at an upstream portion of the attracting member.

15. The image forming apparatus according to claim 14 , wherein the attracting member and the neutralizing member are formed in a single piece structure.

16. The image forming apparatus according to claim 15 , wherein the attracting member and the neutralizing member are parts of a metal plate, and the neutralizing member is formed by bending a portion of the metal plate.

17. The image forming apparatus according to claim 16 , wherein in a cross-sectional view of the image forming apparatus, the attracting member and the neutralizing member have longitudinal axes that are not parallel to each other.

18. The image forming apparatus according to claim 1 , wherein

the print medium is transported in contact with the guide member, and

the attracting member is assembled to the guide member so that the guide member places the attracting member in position relative to the print medium.
