PROBLEM TO BE SOLVED: To solve the problem in which: execution of positional deviation correction and toner discharge respectively as calibration operations causes downtime, which reduces usability.SOLUTION: Control means causes light irradiation means to form an electrostatic latent image for correction and causes developing means to develop the electrostatic latent image as a toner image, so as to control in parallel an operation to control conditions for forming electrostatic latent images during image formation and an operation to supply toner to cleaning means. |
