摘要：
A developer amount detecting method for detecting a developer amount for developing an electrostatic latent image formed on an electrophotographic photosensitive member includes a first process for successively detecting the amount of the developer contained in a containing portion by counting the number of individual image signals for forming dots of an image by a main body of an electrophotographic image forming apparatus; and a second process for successively detecting the developer amount by the apparatus main body by transmitting an electric signal according to the amount of the developer contained in the containing portion to the apparatus main body.
