Abstract
A developer carrying device is provided with a group of carrying electrodes configured to form a traveling wave field as voltages are sequentially applied thereto, charged developer being carried by an effect of the traveling wave field, a developer carrying member having a surface on which the group of carrying electrodes are arranged, and a plurality of leveling electrodes provided above the surface and configured to form electric fields in a direction substantially along the surface, the plurality of leveling electrodes being needle like electrodes extending in a direction intersecting with the surface, the plurality of leveling electrodes being spaced from each other in a direction along the surface and intersecting with a direction in which the developer is carried.
Claims18
A developer carrying device, comprising:
- a plurality of carrying electrodes configured to form a traveling wave field as voltages are sequentially applied thereto, charged developer being carried by an effect of the traveling wave field;
- a developer carrying member having a surface on which the plurality of carrying electrodes are arranged;
- and
- a plurality of leveling electrodes provided above the surface and configured to form electric fields in a direction intersecting with a direction in which the developer is carried, the plurality of leveling electrodes being needle like electrodes with a longest dimension of each extending in a direction intersecting with the surface, the plurality of leveling electrodes being spaced from each other in a direction intersecting with the direction in which the developer is carried.
A developer carrying device, comprising:
- a plurality of carrying electrodes configured to form a traveling wave field as voltages are sequentially applied thereto, charged developer being carried by an effect of the traveling wave field;
- a developer carrying member having a surface on which the plurality of carrying electrodes are arranged;
- and
- a plurality of leveling electrodes provided on the surface and configured to form electric fields in a direction intersecting with the direction in which the developer is carried, the plurality of leveling electrodes being aligned with each other in a direction intersecting with a direction in which the developer is carried.
An image forming device, comprising:
- an electrostatic latent image supporting member, on a surface of which an electrostatic latent image is formed;
- a developer carrying device configured to carry developer to the electrostatic latent image supporting member, the developer carrying device including:
- a plurality of carrying electrodes configured to form a traveling wave field as voltages are sequentially applied thereto, charged developer being carried by an effect of the traveling wave field;
- a developer carrying member having a surface on which the plurality of carrying electrodes are arranged;
- and
- a plurality of leveling electrodes provided above the surface and configured to form electric fields in a direction intersecting with a direction in which the developer is carried, the plurality of leveling electrodes being needle like electrodes with a longest dimension of each extending in a direction intersecting with the surface, the plurality of leveling electrodes being spaced from each other in a direction intersecting with the direction in which the developer is carried;
- and
- a transferring unit configured to transfer the developer, which is supplied from the developer carrying device to the electrostatic latent image supporting part, to a recording medium.
An image forming device, comprising:
- an electrostatic latent image supporting member, on a surface of which an electrostatic latent image is formed;
- a developer carrying device configured to carry developer to the electrostatic latent image supporting member, the developer carrying device including:
- a plurality of carrying electrodes configured to form a traveling wave field as voltages are sequentially applied thereto, charged developer being carried by an effect of the traveling wave field;
- a developer carrying member having a surface on which the plurality of carrying electrodes are arranged;
- and
- a plurality of leveling electrodes provided on the surface and configured to form electric fields in a direction intersecting with the direction in which the developer is carried, the plurality of leveling electrodes being aligned with each other in a direction intersecting with a direction in which the developer is carried;
- and
- a transferring unit configured to transfer the developer, which is supplied from the developer carrying device to the electrostatic latent image supporting part, to a recording medium.
