Abstract
A image forming apparatus includes a rotatable image bearing body, an exposing unit that irradiates the image bearing body to form a latent image, a developer bearing body that develops the latent image to form a developer image, a transfer unit that transfers the developer image to a recording medium, a feeding unit that feeds the recording medium, a density detecting unit that detects a developer density of the developer image transferred to the recording medium, and a speed difference control unit that controls a difference of a circumferential speed of the image bearing body and a feeding speed of the recording medium fed by the feeding unit. The speed difference is controlled based on a density of a thin line pattern transferred to the recording medium detected by the density detecting unit.
Claims8
An image forming apparatus comprising:
- an image bearing body rotatably supported;
- an exposing unit that irradiates said image bearing body to form a latent image;
- a developer bearing body that develops said latent image using a developer to form a developer image;
- a transfer unit that transfers said developer image to a recording medium;
- a feeding unit that feeds said recording medium to a transferring position where said developer image is transferred to said recording medium;
- a density detecting unit that detects a developer density of said developer image transferred to said recording medium, and
- a speed difference control unit that controls a difference of a circumferential speed of said image bearing body and a feeding speed of said recording medium fed by said feeding unit,
- wherein said speed difference control unit controls said difference of said circumferential speed of said image bearing body and said feeding speed of said recording medium based on a density of a thin line pattern transferred to said recording medium detected by said density detecting unit.
An image forming apparatus comprising:
- an image bearing body rotatably supported;
- an exposing unit that irradiates said image bearing body to form a latent image;
- a developer bearing body that develops said latent image using a developer to form a developer image;
- a belt member that bears said developer image;
- a belt driving unit that drives said belt member;
- a density detecting unit that detects a developer density of said developer image on said belt member, and
- a speed difference control unit that controls a difference of a circumferential speed of said image bearing body and a driving speed of said belt member driven by said belt driving unit,
- wherein said speed difference control unit controls said difference of said circumferential speed of said image bearing body and said driving speed of said belt member based on a density of a thin line pattern on said belt member detected by said density detecting unit.
