The present invention provides a flexible light emitter driver circuit which adjusts the luminance of the light emitter diodes by a manual input signal. The stator coil is used in an electric rotating machine. The new variety is a semi-dwarfing rootstock that is resistant to fire blight and crown rot. The second image forming portion includes an image bearing member, a cleaning member that removes transfer residual toner existing on the image bearing member at an abutting position, and a supply unit that supplies abrasive particles or toner to the abutting position. A gap portion is formed between the first and second guide members in a region from the connection portion on the side of the third side surface to the first side surface. Methods of use thereof are also provided.
