Abstract
An image forming apparatus can include a first developing portion having first to fourth developing devices containing yellow, magenta, cyan, and black developers, respectively, each of the first to fourth developing devices being disposed apart from adjacent developing devices of the first to fourth developing devices at a regular interval, a second developing portion to include at least one auxiliary developing device to supplement colors of the first developing portion, and an image carrier to convey images of the first and second developing portions, wherein an interval between the first and second developing portions is a multiple of the regular interval between the first to fourth developing devices.
Claims29
An image forming apparatus, comprising:
- a first developing portion including first to fourth developing devices containing yellow, magenta, cyan, and black developers, respectively, each of the first to fourth developing devices disposed apart from adjacent developing devices of the first to fourth developing devices at a regular interval;
- a second developing portion including at least one auxiliary developing device to supplement colors of the first developing portion;
- and
- an image carrier to convey images of the first and second developing portions,
- wherein an interval between the first and second developing portions is a multiple of the regular interval between the first to fourth developing devices.
An image forming apparatus, comprising:
- a first developing portion including first and second developing devices spaced apart at a regular interval;
- and
- a second developing portion including a third developing device disposed closer to the first developing device than the second developing device;
- wherein the first and second developing portions convey an image to an image carrier, and if an interval between the first and second developing devices on the image carrier is the regular interval, an interval between the first and third developing devices is a multiple of the regular interval.
A developing unit of an image forming apparatus, the developing unit comprising:
- a developing portion having a plurality of developing devices disposed at regular intervals along an image carrier to develop images on the image carrier;
- and
- at least one auxiliary developing device spaced apart from the developing portion at an interval different from the regular interval to supplement the images on the image carrier.
