An electrostatic recording apparatus comprises a photosensitive body whereon an electrostatic latent image is formed and the electrostatic latent image is toner-developed by a developing apparatus. The developing apparatus is fed with a toner from a toner hopper. When at least two of plural operating keys arranged in an operation panel, for example, a copy quantity setting key and a start key, are operated at the same time or in sequence, respondingly, a toner feeding roller is operated for a predetermined time and thereby a predetermined amount of toner can be fed to the developing apparatus from the toner hopper. A key dedicated to command feeding the toner can be dispensed with.
