Abstract

PURPOSE:To avoid toner from being attached to non-exposure part, without using an erase light source, by providing a spiking restriction plate for movable development agent in a developer. CONSTITUTION:A spiking restriction plate 45 makes an operation to limit the amount of development agent attached and carried on a rotary sleeve 42, and when the tip is in contact with the sleeve 42, the attachment and carrying of the development agent is blocked to make no non-exposure part adhered with toner. Spiking restriction plates 45a and 45b are made movable, a restriction of carrying of the development agent for suitable development to the original image is made, and an electromagnetic solenoid 47a is operated to a non-exposed part to make the linear spiking restricting plate 45a contact with the circumference of the sleeve 42 to prevent the development of band shape non-exposure part. Thus, the adhesion of toner on the non-exposure part is prevented without using the light source for erase.
