A CHARGE ROLLER FOR AN IMAGE FORMING APPARATUS USING HARD FILLER PARTICLES
摘要
<p>An image forming apparatus includes a charge roller with improved resistance to defects from prolonged periods of nonuse. The charge roller includes an outermost coating layer including a coating material and filler particles. The filler particles have an average particle size larger than an average thickness of the outermost coating layer in a portion without the filler particles. Furthermore, the filler particles are harder and have a higher glass transition temperature than the coating material.</p>
