Estimating the term…
An image forming apparatus having a developer container containing a developer and a developer carrying member for carrying the developer and adapted to switch an AC voltage to be applied to the developer carrying member, the apparatus comprising a detecting member for detecting the amount of developer in the developer container and a processing portion for determining the amount of developer in the developer container according to the value output by the detecting member when the AC voltage is applied to the developer carrying member, the processing portion being adapted to determine the amount of developer by executing a process that corresponds to the operation of switching the AC voltage.
An image forming apparatus having a developer container containing a developer and a developer carrying member for carrying the developer and adapted to switch an AC voltage to be applied to said developer carrying member, said apparatus comprising:
An image forming apparatus having a developer container containing a developer and a developer carrying member for carrying the developer and adapted to switch an AC voltage to be applied to said developer carrying member, said apparatus comprising:
A method of detecting the amount of residual developer in an image forming apparatus having a developer container containing the developer and a developer carrying member for carrying the developer and adapted to switch an AC voltage to be applied to said developer carrying member, said method comprising:
