    摘要： An image forming apparatus including an image bearing member bearing an electrostatic latent image thereon, a charging device charging the image bearing member, a light irradiating device irradiating the charged image bearing member with light to form the electrostatic latent image, and a developing device developing the electrostatic latent image to form a toner image, wherein the charging time determined by dividing the width of a charging area charged by the charging device in units of mm by the linear velocity of the image bearing member in units of mm/msec is not shorter than the transit time of the image bearing member. The transit time is defined as the time at which an inflection point is firstly observed in a curve showing relationship of the interval between light irradiation and measurement of potential of an irradiated portion with the potential of the irradiated portion, when the interval is shortened.
