<P>PROBLEM TO BE SOLVED: To solve the following problems; an LED head used for a conventional image forming apparatus is integrally fixed to an upper cover as a rule, then, the whole weight of the upper cover is increased and the operability at an opening/closing operation is deteriorated, and also, a space for securing the movement of the LED head is necessary in the image forming apparatus, consequently, a space efficiency is poor and the capacity of a toner cartridge is not made large. <P>SOLUTION: By having such the constitution that an LED head unit 1 is directly attached/detached to/from a developing apparatus 2, the constitution that the LED head is integrally fixed to the upper cover is avoided. <P>COPYRIGHT: (C)2007,JPO&INPIT |
