Abstract
An image forming method comprising; PA1 a charging step of electrostatically charging a photosensitive member; PA1 an exposure step of exposing the charged photosensitive member to form an electrostatic latent image; PA1 a developing step of bringing a toner carried on a developer carrying member, into contact with the surface of the photosensitive member to develop the electrostatic latent image to form a toner image on the photosensitive member; PA1 a transfer step of transferring the toner image formed on the photosensitive member, to a transfer medium; and PA1 a cleaning-at-development step of collecting the toner remaining on the photosensitive member after the transfer step, onto the developer carrying member; PA1 a wherein; PA2 the surface of said photosensitive member has a contact angle with water of 85.degree. or greater; PA2 said toner contains residual monomers in an amount not more than 1,000 ppm; and PA2 said toner has a shape factor SF-1 of from 100 to 180 and a shape factor SF-2 of from 100 to 140.
