An image forming apparatus includes a connecting device to which a charging apparatus is connected, an image forming device, an operating device, and a control device. The control device functions as an operation accepter, a controller, a charging processor, and a notifier. The notifier performs a processing for giving a first notice; the first notice is for asking a user whether or not to donate all of or part of a remaining money which is remaining, posterior to charging for a print job, in an inserted amount of money. After the notifier has performed the processing for giving the first notice, when the operation accepter accepts an instruction of execution of the donation, the charging processor performs a charging processing by subtracting, from the inserted amount of money, a charging amount for the print job and an amount of donation indicated by the instruction of execution of the donation.
