摘要： A controller which causes a light emitting element to continuously perform minute emission for a plurality of dots in a level in which toner is not attached to a non-image section on an image bearing member is provided. The controller controls a first driving current for an image section and controls a second driving current used to perform the minute emission by the light emitting element in the non-image section several times in one job. In the image section, a driving current obtained by adding the first driving current to the second driving current is supplied so that the light emitting element emits light.

摘要： An image forming apparatus includes a plurality of image forming stations and a control portion configured to control an image forming operation. Each of the image forming stations includes an image bearing member configured to form a toner image on a surface thereof and a charging device configured to charge the image bearing member. The toner images formed on the image bearing members of the image forming stations are sequentially transferred to a transfer incurring member to be superimposed. The control portion sets a voltage applied to the charging device in forming an image in an image forming station which performs the transfer later based on image density information of the toner image transferred to the transfer incurring member by an image forming station which performs the transfer earlier in a sequence of the image forming operations.
