发明名称 Image forming apparatus which controls a transfer bias to a leading edge of a recording medium
摘要 An image forming apparatus including a latent image bearing member, a charger to evenly charge a surface of the latent image bearing member, an electrostatic latent image forming device to form an electrostatic latent image on the surface of the latent image bearing member, a developing device to develop the electrostatic latent image into a toner image using toner, a transfer bias application device to apply a transfer bias to an image transfer area where the latent image bearing member faces a recording medium, a pre-transfer neutralizing device to reduce an electric potential at a portion on the surface of the latent image bearing member, a surface electric potential detector to detect an electric potential at the surface of the latent image bearing member, and a radiation amount control device to control an amount of radiation from the pre-transfer neutralizing device.
