Abstract:
1. An image forming apparatus comprising: a color developing device for developing with a color toner an electrostatic image formed on a photosensitive member, said color developing device including a fixed magnet provided with a plurality of magnetic poles, a developer carrying member which is rotated around the fixed magnet and carries a color developer comprising a color toner and a carrier, and a layer thickness regulating member which is provided opposed to the developer carrying member and regulates a layer thickness of the carried color developer; and a transparent developing device for developing with a transparent toner an electrostatic image formed on a photosensitive member, said transparent developing device including a fixed magnet provided with a plurality of magnetic poles, a developer carrying member which is rotated around the fixed magnet and carries a transparent developer comprising a transparent toner and a carrier, and a layer thickness regulating member which is provided opposed to the developer carrying member and regulates a layer thickness of the carried transparent developer, wherein a distance from a downstream one of adjacent magnetic poles of the same polarity of the fixed magnet of said transparent developing device with respect to a developer carrying member rotational direction to a position opposing the layer thickness regulating member is longer than a distance from a downstream one of adjacent magnetic poles of the same polarity of the fixed magnet of said color developing device with respect to the developer carrying member rotational direction to the position opposing the layer thickness regulating member.
