Laser driving control apparatus, drying apparatus, image forming apparatus, computer readable medium storing laser driving control program, and computer readable medium storing drying program

A non-transitory computer readable medium storing a drying program causing a computer to execute a process for drying, the process comprising:

• constant-voltage driving a laser light source that radiates laser light by supplying a pulse signal in which a plurality of pulses, each pulse width thereof being changeable, is generated at a predetermined cycle;
• performing control to change the pulse width of each of the plurality of pulses of the pulse signal so that a first change amount of the pulse width at a time when a present-time pulse width is changed to a preceding pulse width prior to reaching a pulse width at which a target light quantity is obtained stably is larger than a second change amount of the pulse width at a time when the present-time pulse width is changed to a target pulse width corresponding to a driving current at an ON time of the laser light source in a steady state in which the target light quantity is obtained stably;
• and
• performing control, in case that at least part of an image region formed by liquid drops ejected according to image information is included in a radiation region of the laser light radiated from the laser light source, so as to control the laser light source with a duty turning ON/OFF the laser light source so that the light quantity corresponding to a drying light quantity having been set as a light quantity for drying the liquid drops is obtained.
