Abstract
A developing device confronting a rotatably provided electrostatic latent image support member and including a rotatable developing roller confronting said electrostatic latent image support member, a flexible outer sleeve having a peripheral length larger than that of the developing roller so as to be loosely fitted around the developing roller, an urging member for depressing the outer sleeve against the developing roller so as to form a gap between the developing roller and the outer sleeve such that a peripheral surface of the outer sleeve is brought into contact, at a downstream side or an upstream side of its location having a maximum distance from an axis of the developing roller in a rotational direction of the outer sleeve, with the electrostatic latent image support member when the developing roller is rotated and a member for forming a toner layer on the peripheral surface of said outer sleeve.
