Abstract
An image forming apparatus according to the present embodiment comprises: a dither processing unit that applies a dither matrix to an image; an exposure unit that exposes an photosensitive drum to form an electrostatic latent image, based on the image to which the dither matrix has been applied; a development unit that develops, using a developing material on a developing roller, the formed electrostatic latent image; and a control unit that, based on a print setting change instruction by a user, increases a circumferential speed of the developing roller relative to the circumferential speed of the photosensitive drum and decreases a screen ruling of the dither matrix to be applied by the dither processing unit.
Claims5
An image forming apparatus, comprising:
- a dither processing unit that applies a dither matrix to an image;
- an exposure unit that exposes a photosensitive drum to form an electrostatic latent image, based on the image to which the dither matrix has been applied;
- a development unit that develops, using a developing material on a developing roller, the formed electrostatic latent image;
- and
- a control unit that, based on a print setting change instruction by a user, increases a circumferential speed of the developing roller relative to a circumferential speed of the photosensitive drum and decreases a screen ruling of the dither matrix to be applied by the dither processing unit.
An image forming apparatus, comprising:
- a dither processing unit that applies a dither matrix to an image;
- a forming unit that forms the image, to which the dither matrix has been applied, onto a sheet;
- and
- a control unit that, based on a print setting change instruction by a user, causes a maximum density to be formed in the forming unit to increase and decreases a screen ruling of the dither matrix applied by the dither processing unit.
An image forming apparatus, comprising:
- a dither processing unit that applies a dither matrix to an image;
- a forming unit that forms the image, to which the dither matrix has been applied, onto a sheet;
- and
- a control unit that, based on a print setting change instruction by a user, causes a maximum density to be formed in the forming unit to increase and changes a threshold of the dither matrix to be applied by the dither processing unit.
