PURPOSE: To facilitate the attachment/detachment of a cleaner unit. CONSTITUTION: The cleaner unit B is freely attachably/detachably held by a first support 46, one end of it is supported to be freely turnable on a supporting shaft 50 by an upper frame 3 and the other end is freely movably supported by the guide 52 of a lower frame 1, with a projecting shaft 51 and engaged with the upper frame 3. When the engagement of the first support 46 with the upper frame 3 is released to open it, one end of the first support 46 is raised together with the upper frame 3, in a state where the projecting shaft 51 of the first support 46 is engaged with the translot 53 of the guide 52, so that the cleaner unit B becomes an attachable/detachable state where the cleaner unit B is exposed to an opening formed by the upper and lower frames 3 and 1, in such a manner that an opening 43 facing a photoreceptor 10 faces upward. |
