Image forming apparatus and toner
First Claim
1. An image forming apparatus comprising:
- an image support body configured to support a latent image;
a charging member configured to provide a substantially uniform charge to a surface of the image support body;
a spacer coupled to said charging member and configured to contact said image support body to maintain a gap between the image support body and the charging member;
an exposing part configured to expose the charged surface of the image support body to write the latent image based on image data;
a developing part configured to develop the latent image by supplying toner particles to the latent image formed on the surface of the image support body to make the latent image a visible image;
a transferring part configured to transfer the visible image on the surface of the image support body onto a transferring medium;
a cleaning part configured to clean the surface of the image support body after the transferring, said cleaning part being configured to satisfy the relationship A+B≦
C, where A is a width of the effective charging area of the charging member that charges a surface of the image support body, B is a total width of the spacer that contacts the image support body, and C is a width of cleaning part that contacts the image support body.

Abstract
An image forming apparatus having an image support body configured to support a latent image, a charging member configured to provide a substantially uniform charge to a surface of the image support body and a spacer coupled to the charging member and configured to contact the image support body to maintain a gap between the image support body and the charging member. A cleaning part is configured to clean the surface of the image support body after developer is applied to the image support body and transferred to a recording medium. The cleaning part is configured to satisfy the relationship A+B≦C, where A is a width of the effective charging area of the charging member that charges a surface of the image support body, B is a total width of the spacer that contacts the image support body, and C is a width of cleaning part that contacts the image support body.

16. An image forming apparatus comprising:
-
an image support body configured to support a latent image;
means for charging a surface of the image support body uniformly;
means for maintaining a gap between the image support body and the means for charging;
means for exposing the charged surface of the image support body to write a latent image based on image data;
means for developing the latent image by supplying toner particles to the latent image formed on the surface of the image support body to make the latent image a visible image;

17. A method for producing improved images in an image forming apparatus, comprising:
-
positioning a charging member adjacent to an image support body, the charging member being configured to charge a surface of the image support body;
providing a spacer in contact with said charging member and image support body such that an area of the charging member is maintained at a gap distance from an area of the image support body;
providing a cleaning member in contact with said image support body, the cleaning member having a predetermined width that reduces an amount of toner particles that can bond to the spacer during image formation such that said gap distance is maintained substantially constant over time. - View Dependent Claims (18, 19, 20, 21)
