Abstract:
1. An image forming apparatus comprising: light color toner image forming means for forming a light color toner image on a transferring medium with a light color toner, said light color toner image forming means including: a first image bearing member; a first developing device for developing an electrostatic image on said first image bearing member in a first developing portion to form the light color toner image on said first image bearing member; and a first transferring member for electrostatically transferring the light color toner image to the transferring medium by abutting against said first image bearing member through the transferring medium at a first abutment portion; and deep color toner image forming means for forming a deep color toner image on the transferring medium with a deep color toner having a same hue as the light color toner and having a brightness less than a brightness of the light color toner, said deep color toner image forming means including: a second image bearing member; a second developing device for developing an electrostatic image on said second image bearing member in a second developing portion to form the deep color toner image on said second image bearing member; and a second transferring member for electrostatically transferring the deep color toner image to the transferring medium by abutting against said second image bearing member through the transferring medium at a second abutment portion, said second transferring member being arranged so that a distance in a rotational direction of said second image bearing member between said second developing portion and said second abutment portion is longer than a distance in a rotational direction of said first image bearing member between said first developing portion and said first abutment portion, and said deep color toner image forming means is arranged upstream of a direction of movement of said transferring medium with respect to said light color toner image forming means.
