Multi-pass type image forming apparatus

An image forming apparatus including a photosensitive body and a plurality of developing devices to develop a color image on the photosensitive body, comprising:

• at least one fixed-position developing device;
• and
• at least one first moving developing device and at least one second moving developing device,
• wherein when the first moving developing device moves away from a development position on the photosensitive body, the second moving developing device moves to the development position, and
• wherein one of the first moving developing device and the second moving developing device is a linear developing device that moves linearly to/from the development position, and the other one of the first moving developing device and the second moving developing device is a rotating developing device which rotates to/from the development position.

An image forming apparatus including a photosensitive body and a plurality of developing devices to develop a color image on the photosensitive body comprising:

• one or more fixed-position developing devices that have fixed positions relative to the photosensitive body;
• and
• a plurality of moveable developing devices that change position relative to the photosensitive body,
• the plurality of moveable developing devices comprising:
• at least one first developing device and at least one second developing device,
• wherein when the first developing device moves away from a development position on the photosensitive body, the second developing device moves to the development position, and
• wherein at least one of the first developing device and the second developing device is a linear developing device which moves in a linear direction, and at least the other one of the first developing device and the second developing device is a rotating developing device which rotates.

An image forming apparatus comprising:

• a photosensitive body;
• and
• a plurality of developing devices disposed to form a plurality of gap areas with the photosensitive body to supply a plurality of developers to the photosensitive body,
• wherein a plurality of lines that connect a first predetermined position on the photosensitive body to second predetermined positions on the plurality of developing devices form a plurality of angles with each other, and at least one of the plurality of angles is different from the other angles,
• wherein the plurality of developing devices comprise a fixed-position developing device and a plurality of moveable developing devices, and where the at least one of the plurality of angles is an angle between the lines of the fixed-position developing device and at least one of the plurality of moveable developing devices,
• wherein one of the plurality of moving developing devices is a linear developing device that moves linearly to/from a development position, and another one of the plurality of moving developing devices is a rotating developing device which rotates to/from the development position.
