An elastic rotatable member conveniently usable as an image fixing member has a base member, a first primer layer, an elastic layer, a second primer layer and a resin layer in the order named. The first primer layer has a thermal conductivity higher than that of the second primer layer. Using the elastic rotatable member, its sheet conveying properties, releasability, wear resistance and durability are improved. When used for an image fixing rotatable member, its image fixing properties are improved.

Elastic rotatable member and fixing apparatus

There is disclosed an apparatus for obtaining image signal by tonal processing of an input signal. Pulse-width modulation of the input signal is achieved thorugh comparison with a second signal of a predetermined shaped, for example a triangular signal. In order to avoid the influence of fluctuating factors in pulse-width modulation, the apparatus also has a third signal generator, and the pulse-width modulated signal or a pattern signal generated by the third signal generator is selectively used for image formation.
