Abstract: An image forming apparatus such as an electrophotographic copying apparatus has a latent image carrier and a cleaning unit which can be drawn together out of the apparatus housing. After the latent image carrier and the cleaning unit has been pulled out, the cleaning unit is angularly moved around the latent image carrier to direct its cleaning position or slot upwardly. Then, the latent image carrier and the cleaning unit are separated from each other. Since the cleaning slot is directed upwardly, toner collected in the cleaning unit will not be spilled or scattered around through the cleaning slot. The cleaning unit may be coupled with a toner cartridge for collecting toner from the cleaning unit.
