彩色激光打印机的成像原理和黑白激光打印机一样（成像6步完全相同，分别为：1.充电，2.曝光，3.显影，4.转印，5.定影，6.清洁）都是先对成像鼓进行充电，利用激光扫描，在硒鼓上形成静电潜影，然后吸附墨粉，再将墨粉转印到打印纸上。只不过黑白激光打印机只有一种黑色墨粉。具体原理图如下：

而彩色激光打印机要使用黄、品、青、黑四种颜色的墨粉。基于CMYK色系，每次处理一种颜色。这四个打印循环有两种处理方法。早期是利用转印胶带，每处理一种颜色，将墨粉从硒鼓转到转印带上，然后清洁硒鼓再处理下一种颜色，最后在转印带上形成彩色图像，再一次性地转印到纸张上，经加热固着；目前普遍的方法是四色硒鼓相同工作，处理完一种色彩，墨粉就吸附在硒鼓上，接着处理下一种色彩，最后一次性地转印到打印纸上。原理图如下：
