Abstract
A method of preventing a flow pattern in a wet-type color image forming apparatus and a system adopting the same includes a material layer directly contacting a developing roller of a developing unit of a photosensitive body of the image forming apparatus and having a thickness of 7-15 μ. A size of an essential composition used for representing corresponding one of colors in high-concentration ink is 0.7-1.5 μm. A hold up volume is not formed between the developing roller and the photosensitive body during a developing process, and a flow pattern such as a stripe, is not formed in a final image, and even though the flow pattern is formed in the final image, the flow pattern can be minimized.
Claims21
A wet-type color image forming apparatus having a developing unit to develop a latent electrostatic image corresponding to external input data, comprising:
- a photosensitive body having the latent electrostatic image to be developed by high-concentration ink supplied from the developing unit, and having a solid center body and a contour layer surrounding a circumference of the center body, wherein a layer contacting the developing unit of the contour layer is a flow pattern-prevention layer having a thickness of less than 25 μm to prevent a flow pattern from being formed on the developed latent electrostatic image.
A method of preventing a flow pattern in a wet-type color image forming apparatus having a latent electrostatic image, the method comprising:
- forming the latent electrostatic image on a photosensitive body having a flow pattern-prevention layer having a thickness of less than 25 μm inclusive;
- and
- developing the latent electrostatic image on the flow pattern-prevention layer of the photosensitive body by using high-concentration ink supplied from a developing unit to prevent a flow pattern from being formed on the developed latent electrostatic image.
An apparatus in a wet-type color image forming apparatus having a developing unit to develop a latent electrostatic image, comprising:
- a photosensitive body having the latent electrostatic image to be developed by high-concentration ink supplied from the developing unit;
- and
- an outmost layer formed on the photosensitive body to contact the high-concentration link, having a thickness of less than 25 μm
