摘要： A developing device has a rotatable developer holding cylinder and a developing device box for supporting the developer holding cylinder. The developing device box is freely suspended by a holding device, and pressure is resiliently applied to the cylinder so that the cylinder is maintained at a predetermined close distance with respect to a rotatable image bearing member. The position at which the developing device box is suspended is set to a position at which a force component of the driving force transmitting the rotational movement of the image bearing member to the developer holding cylinder acts in a direction in which the cylinder moves away from the image bearing member.

摘要： Apparatus for fixing toner image on a toner image supporting member in electrophotographic copying machine is disclosed. The fixing apparatus includes three rotary rollers which are in contact with each other under the action of pressing means. One of the three rollers has a smaller diameter than the other two rollers. Two rollers with which the toner image supporting member comes into contact are disposed in such a manner that the axes of the two rollers intersect each other and the portion at which the two rollers contact each other or are closest to each other forms a straight line relative to the direction of roller axis. According to one embodiment of the invention, the remaining one roller with which the supporting member does not contact, is formed as a crown roller, that is, a roller which has its largest diameter at the middle portion of the roller.
