Abstract
Provided is an image forming apparatus including voltage applying unit for applying voltages to a developer carrier in which a surface that carries a developer is configured so that a plurality of dielectric portions is interspersed on a surface formed of a conductor portion, and to a regulating member that regulates a layer thickness of the developer that is carried on the developer carrier. The voltage applying unit has a period, during non-image formation, over which voltage such that an absolute value of potential difference between voltage applied to the developer carrier and voltage applied to the regulating member is greater than that during image formation is applied to at least one of the developer carrier and the regulating member.
Claims10
An image forming apparatus, comprising
- a developing apparatus including:
- a container that holds a developer;
- a developer carrier in which a surface that carries the developer is configured so that a plurality of dielectric portions is interspersed on a surface formed of a conductor portion;
- and
- a regulating member that regulates a layer thickness of the developer that is carried on the developer carrier,
- the image forming apparatus forming an image on a recording material by developing, using the developing apparatus, an electrostatic latent image formed on an image bearing member to yield a developer image, and transferring the developer image from the image bearing member to the recording material,
- the image forming apparatus further comprising:
- voltage applying unit for applying voltages to the developer carrier and the regulating member,
- wherein the voltage applying unit has a period, during non-image formation, over which voltage such that an absolute value of potential difference between voltage applied to the developer carrier and voltage applied to the regulating member is greater than that during image formation is applied to at least one of the developer carrier and the regulating member.
