摘要： In an image forming apparatus for forming an electrostatic latent image corresponding to an image signal and for developing the latent image, a signal value corresponding to an amount of toner consumed by the development is counted by using the image signal. A toner supplement mechanism is controlled on the basis of the signal value, and an error component of the counted signal value. In addition, toner is supplied based on the counted signal value or a detected toner density in accordance with the number of image formations.

摘要： In an image recording apparatus having a recording head, recording may be interrupted (for example, to permit transfer of new image data after a predetermined amount of recording is performed). Recording quality is maintained by compensating for the change in head temperature which occurs during the interruption. This is done by detecting the temperature of the recording head and/or counting the interruption time, and driving the recording head in a stand-by mode or correcting the image signal in accordance with the temperature difference between interruption and resumption of recording.
