Abstract
An image forming apparatus includes: a first developing member that develops a first toner image on a first image carrier with a brilliant toner containing a flat pigment; a second developing member that develops a second toner image on a second image carrier with a non-brilliant toner containing no brilliant pigment; and a controller that controls the first developing member and the second developing member. The controller controls a development efficiency of the brilliant toner of the first developing member to be lower than a development efficiency of the non-brilliant toner of the second developing member.
Claims15
An image forming apparatus comprising:
- a first developing member that develops a first toner image on a first image carrier with a brilliant toner containing a flat pigment;
- a second developing member that develops a second toner image on a second image carrier with a non-brilliant toner containing no brilliant pigment;
- and
- a controller that controls the first developing member and the second developing member,
- wherein the controller controls a development efficiency of the brilliant toner of the first developing member to be lower than a development efficiency of the non-brilliant toner of the second developing member.
An image forming apparatus comprising:
- a first developing member that develops a first toner image on a first image carrier with a brilliant toner containing a flat pigment;
- a second developing member that develops a second toner image on a second image carrier with a non-brilliant toner containing no brilliant pigment;
- a transfer unit that transfers the first toner image and the second toner image onto a transfer body;
- and
- a controller that controls the first developing member and the second developing member,
- wherein when superimposing the first toner image and the second toner image on each other on the transfer body, the controller controls a development efficiency of the brilliant toner of the first developing member to be lower than when forming the first toner image on the transfer body without superimposing the first toner image and the second toner image on each other on the transfer body.
An image forming apparatus comprising:
- a first developing member that develops a first toner image on a first image carrier with a brilliant toner containing a flat pigment;
- a first charging member that charges the first image carrier;
- a first supply member that supplies the brilliant toner to the first developing member;
- and
- a controller that controls bias voltages applied to the first developing member, the first charging member, and the first supply member,
- wherein the controller makes a development efficiency of the brilliant toner of the first developing member lower than the development efficiency when the bias voltage applied to the first developing member is −185 V, the bias voltage applied to the first charging member is −1111 V, and the bias voltage applied to the first supply member is −489 V.
