A developer in use with an image forming apparatus. The developer includes: a developing sleeve which rotates and holds toner on itself so as to develop a latent image on a photoreceptor with the toner; a driving motor for generating a rotational driving force; a drive transmission for transmitting the rotational driving force of the driving motor to the developing cartridge in which the drive transmission has a transmitting state and an untransmitting state; and a shock easing controller or member for easing a shock of transmission of the rotational driving force to the developing sleeve in the transmitting state, in which the shock easing controller or member is provided in at least one of the driving means and the drive transmission means.

Developing apparatus in use with an image forming apparatus

In a device for fixing a toner image on a sheet in an image forming apparatus, a pair of pulling rollers is disposed downstream of a heating roller in the direction to convey the sheet and is rotated at a peripheral speed higher than that of the heating roller.

Fixing device with pulling rollers

This invention discloses a developing apparatus wherein a brush of a developing agent is formed on a developing sleeve by a magnetic field of a permanent magnet disposed inside the developing sleeve, and at least the developing sleeve is rotated while the brush is kept in contact with a photosensitive body, thereby developing an electrostatic latent image formed on the photosensitive body. In this apparatus, an agitating member having magnetic ring portions which abut against the developing sleeve and an agitating portion for agitating the developing agent is pivotally disposed in a developing vessel to be parallel to the developing sleeve, and a rotation detecting unit for outputting a signal corresponding to a rotational speed of the agitating member and a residual amount detecting unit for detecting a residual amount of the developing agent in the developing vessel in accordance with an output from the rotation detecting unit are provided.
