Abstract:
1. An image forming apparatus comprising: a forming unit that forms a latent image of input image data; a counter that counts number of times of forming the latent image in a sub-scanning direction, in which an upper limit of the number of times is set; a first control unit that controls the forming unit to form the latent image based on the upper limit; a determining unit that determines whether a latent image forming is performed by the forming unit exceeding the upper limit; and a second control unit that controls, when the determining unit determines that the latent image forming is performed exceeding the upper limit, the forming unit to continue to form the latent image, wherein the determining unit makes a determination based on a flag that indicates whether the latent image forming is performed exceeding the upper limit, and wherein when the flag is in an active state, the second control unit validates a sub-scanning image-data transfer valid area, a sub-scanning write valid area, and a sub-scanning write trim area independently of a control by the counter.
