Abstract
An electrostatic charging apparatus includes: an electrostatic charging member that has a discharge face causing discharge between the electrostatic charging member and a to-be-charged member having a charge retention part to hold a charge, and comes in contact with the to-be-charged member so as to charge upon the application of voltage; and an adjusting unit that adjusts an angle between the to-be-charged member and the discharge face.
Claims8
An electrostatic charging apparatus comprising:
- an electrostatic charging member that has a discharge face causing discharge between the electrostatic charging member and a to-be-charged member having a charge retention part to hold a charge, and comes in contact with the to-be-charged member so as to charge upon the application of voltage;
- an adjusting unit that adjusts an angle between the to-be-charged member and the discharge face;
- and
- a control unit that controls the adjusting unit so as to reduce the angle between the to-be-charged member and the discharge face in response to increasing the number of times of electrostatic charging.
An electrostatic charging apparatus comprising:
- an electrostatic charging member that has a discharge face causing discharge between the electrostatic charging member and a to-be-charged member having a charge retention part to hold a charge, and comes in contact with the to-be-charged member so as to charge upon the application of voltage;
- and
- an adjusting unit that adjusts an angle between the to-be-charged member and the discharge face;
- wherein the electrostatic charging member is flexible and endless-shaped;
- and
- the adjusting unit is arranged inside the electrostatic charging member, has a support to support the electrostatic charging member, and adjusts the angle between the to-be-charged member and the discharge face by moving the support.
An electrostatic charging member that has a discharge face causing discharge between the electrostatic charging member and a to-be-charged member having a charge retention part to hold a charge, and comes in contact with the to-be-charged member so as to charge upon the application of voltage;
- and
- an adjusting unit that adjusts an angle between the to-be-charged member and the discharge face;
- wherein the electrostatic charging member is belt-like;
- and
- the adjusting unit has a contact member to come in contact with the electrostatic charging member from the to-be-charged member side and adjusts the angle between the to-be-charged member and the discharge face by moving the contact member.
