Image forming apparatus

An image forming apparatus, comprising:

• an image bearer;
• a charging member to charge the surface of the image bearer;
• an irradiating member to irradiate the surface of the image bearer to form an electrostatic latent image on the surface of the image bearer;
• a developing member to develop the electrostatic latent image with a toner to form a visible toner image on the surface of the image bearer;
• and
• a transferring member to transfer the toner image onto a transfer material,
• wherein the image bearer includes a charge generation layer including an asymmetrical disazo pigment and a metal-free phthalocyanine pigment, and a charge transport layer,
• wherein the irradiating member forms the electrostatic latent image at an irradiation energy greater than a half decay exposure of the image bearer and not greater than 2.5 times of the half decay exposure, and
• wherein the image bearer is not discharged every image forming process, and
• wherein the irradiating member irradiates the image bearer in synchronization with a transfer bias being turned off to discharge the surface of the image bearer after at least two image forming processes are completed.
