摘要： A method of adjusting line data is provided, where a dot pattern for one line is represented by dot data indicative of dot formation and blank data indicative of no dot formation. The method includes: determining whether X or more blank data are arranged consecutively, the X or more blank data including adjacent blank data adjacent to dot data on at least one side of the dot data, where X is an integer greater than or equal to one (X≧1); and converting Y consecutive blank data including the adjacent blank data into dot data if it is determined that the X or more blank data are arranged consecutively in the determining step, where Y is an integer greater than or equal to one and less than or equal to X (X≧Y≧1).

摘要： A forming-dot counting section counts a number of dots of a subject color based on dot pattern data of the subject color. An overlapping-dot counting section compares the dot pattern data of the subject color and the dot pattern data of at least one other color of which dots are formed prior to the subject color, and counts a number of overlapping dots of the subject color that are formed in an overlapping relation with the dots of the at least one other color. A calculating section calculates the amount of adhering toner of the subject color by subtracting an estimated amount of non-adhering toner from an estimated amount of adhering toner. The estimated amount of adhering toner is estimated based on the number of dots of the subject color. The estimated amount of non-adhering toner is estimated based on the number of overlapping dots.

摘要： A light receiving sensor receives laser light scanned by a light deflector and generates a detection signal. A pseudo-signal generating section generates a pseudo signal having a cycle that has the same length as a generation cycle of the detection signal. A lighting control section controls lighting start timing at which a light emitting element starts lighting based either on the detection signal or on the pseudo signal. A condensation determining section determines whether possibility that condensation occurs at the light receiving sensor is high based on a predetermined criterion. A malfunction determining section determines that the light receiving sensor has malfunction if the light receiving sensor fails to generate the detection signal within a predetermined period. A lighting control section controls the lighting start timing based on the pseudo signal, if it is determined that the possibility is high and that the light receiving sensor has malfunction.
