Abstract:
A process for development, which comprises:using a non-magnetic toner having a circularity degree of more than 0.94 and having a falling amount, determined by a tester, of at least 10 g/5 minutes,feeding the above toner via a sub-roller onto a development roller disposed against a photosensitive drum, wherein rotating directions of the development roller and the sub-roller are prescribed in a downward direction at a portion where these rollers face each other,forming a thin layer of the toner on the development roller by a blade press-contacted with the development roller, andcontacting the thin layer of the toner with a surface of the photosensitive drum on which an electric latent image is formed, to perform the development of the electrostatic latent image.
