Abstract

An electrostatic latent image is developed with a developer comprising toner particles having a lower size limit of 3 mu m and an upper size limit of 8 to 15 mu m and carrier particles of a size which is not less than the upper size limit of the toner particles and not greater than 65 mu m. After the image is transferred to plain paper it is flush fixed.
