摘要： In an image forming apparatus adapted to form images by employing a plurality of image bearing members, when a monocolor mode is selected, no toner image is formed on photosensitive drums of the colors other than the photosensitive drum on which a black toner image is formed. However, the photosensitive drums of the remaining colors continue to run while maintaining a speed difference in a four-full-color mode in relation to an intermediary transfer belt. As a result, some photosensitive drums reach their service life even if the toners contained in developing devices have not yet run out or even if images have not yet been formed on a predetermined number of transfer materials. To solve the problem, the peripheral speed of each of the photosensitive drums in the black monocolor mode for producing monochrome images is set to be faster than that in the full-color mode so as to make the peripheral speed virtually equal to the moving speed of the intermediary transfer belt.

摘要： A multivalued input recording signal is subjected to pulse-width modulation at a time unit shorter than the period of a clock signal within the period of the recording signal. Alternatively, the multivalued input recording signal is converted into a plurality of different signals each of whose length of time is shorter than a clock signal within the period of the recording signal, thereby performing pulse-width modulation in accordance with a predetermined weighting. This makes it possible to obtain a highly toned recording signal without raising the frequency of the clock signal. Further, density tone data is generated in dependence upon inputted multivalued pixel data, and control is performed using both the irradiation time and emission intensity of a light beam based on the generated density tone data. An image is formed by irradiating a photosensitive body with the controlled light beam.
