にしたものである。Conventionally, electronic copying machines are equipped with a cleaning device for the purpose of removing untransferred toner remaining on the surface of the photoreceptor after the transfer process, and many of these cleaning devices are not finned.
An elastic blade is used to remove the toner. The base end of the above elastic blade is held by a holding member so that the tip is in line contact with the surface of the photoreceptor at an acute angle.In order to attach the elastic blade and the holding member, hold the base 4 parts of the elastic blade. Methods such as sandwiching the parts between parts and tightening them with screws or gluing them at multiple locations were used. However, with the former method, when tightening with screws 7, the holding member is compromised in the longitudinal direction, causing deformation of the tip of the elastic blade, and with the latter method of gluing, the elastic blade may be deformed depending on the degree of friction. However, there was a problem in that the tip of the elastic blade did not come into uniform contact with the photoconductor, and as a result, the untransferred residual toner on the photoconductor could not be completely removed.This invention was made with the aim of improving this drawback. The following is a cleaning DTLT machine for an electronic copying machine in which an elastic blade is supported so as to be rotatable in three-dimensional directions, so that the optical layer of the elastic blade is always in uniform contact with the surface of a photoreceptor.
