Need to Set Minimum and Maximum Level of Logging in Log4j

My requirement is little weird.

I want different formatting pattern for different Logging levels that's why I have used this code. But I am unable to set the min and max limit. Because when I am setting logging level to Debug, it is also printing the ERROR and FATAL log messages in that format but I have defined a different format for ERROR and FATAL and because of this ERROR messages are printing two times for this code. I do not want to print ERROR and FATAL log messages in DEBUG pattern format. 

log4j.rootLogger=DEBUG, infoLog, errorLog

log4j.appender.infoLog=org.apache.log4j.ConsoleAppender
log4j.appender.infoLog.Target=System.out
log4j.appender.infoLog.layout=org.apache.log4j.PatternLayout
log4j.appender.infoLog.layout.ConversionPattern=%m%n
#log4j.appender.infoLog.Threshold=DEBUG
log4j.appender.infoLog.filter.a=org.apache.log4j.varia.LevelRangeFilter
log4j.appender.infoLog.filter.a.LevelToMatch=INFO
log4j.appender.infoLog.filter.a.AcceptOnMatch=true
log4j.appender.infoLog.filter.a.LevelMin=DEBUG
log4j.appender.infoLog.filter.a.LevelMax=INFO

#log4j.appender.infoLog.filter.b=org.apache.log4j.varia.LevelMatchFilter
#log4j.appender.infoLog.filter.b.LevelToMatch=DEBUG
#log4j.appender.infoLog.filter.b.AcceptOnMatch=true

log4j.appender.errorLog.Threshold=ERROR
log4j.appender.errorLog=org.apache.log4j.ConsoleAppender
log4j.appender.errorLog.Target=System.out
log4j.appender.errorLog.layout=org.apache.log4j.PatternLayout
log4j.appender.errorLog.layout.ConversionPattern=\u001b[31;1m%d{yyyy-MM-dd HH:mm:ss} [%-5p] %c{1}:%M():%L - %m%n
