<p>PURPOSE:To obtain a uniform image by adjusting the rotation of a feed roller and the voltage of a bias power source, thereby changing according to the rotating speed of the feed roller an amount that toner particles stick to an electrostatick latent image, and eliminating density irregularites on recording paper. CONSTITUTION:On the point of cutting the recording paper 21 after feeding it only a prescribed length, a control part 33 suppresses the operation of a drive motor 29, decreases the rotating speed of the feed roller 22, also controls the operation of a bias power source 32, and moderately applies minute negative potential to a developing unit 24. Consequently, in the developing unit 24, electrons are generated around toner, and an amount that toner particles stick to an electrostatic latent image is decreaced. On the other hand, the recording paper 21 is cut by a cutter 26. Thus, even when the speed of the feed roller 22 is decreased to cut the paper 21, on which recording has been carried out, uniform development can be performed.</p> |
