An image forming apparatus which forms an image on a recording medium, includes: a belt which is endless and rotationally driven; a drive roller which is wound around the belt to rotationally drive the belt; a position detector which is arranged along an axial direction of the drive roller to detect deviation of the belt; a steering roller which is wound around the belt and corrects the deviation of the belt detected by the position detector; and a controller which controls the steering roller, wherein the controller determines a deterioration state of the belt based on a change amount linked with change of a friction coefficient of the belt until a predetermined period elapses after starting use of the belt.

Image forming apparatus and non-transitory recording medium storing computer readable program

A writing device to write an image onto a photoconductor, including a print head having plural LEDs, a first supporting member, having a position determining section to determine the position of the print head, and an adjustment screw, and a second supporting member, having a reference shaft which comes into contact with the first supporting member and movably supports the first supporting member while moving to or separating from the photoconductor, and a pressuring member which presses the first supporting member against the reference shaft, wherein the second supporting member is engaged with the first supporting member by the adjustment screw, whereby when the adjustment screw is rotated, the print head is shifted along with the first supporting member, and a first direction joining the position determining section and the adjustment screw makes a right angle with a second direction joining the adjustment screw and the reference shaft.

Writing device

An image forming apparatus includes: a photoreceptor; a charger that electrically charges the photoreceptor; an exposing unit having an LED printing head that forms a latent image on the photoreceptor; a developing unit that develops a toner image corresponding to the latent image on the photoreceptor; a blower unit that sends air to a space between the photoreceptor and the LED printing head; a first shielding member provided on the charger, which intercepts the air coming from the blower unit to enter inside the charger; and a second shielding member provided on the developing unit, which intercepts the air coming from the blower unit to enter inside the developing unit.
