Abstract:
A developing device includes a developer accommodating casing, a developer carrying member, a regulating portion, a magnetic flux generating portion, and a cover portion. A first opposing region between the casing and the developer carrying member is downstream of the developing region and upstream of a second opposing region between the cover portion and the developer carrying member with respect to a rotational direction. The following relationships are satisfied: L 1≤ L 2+ L 3,  and L 2≤ L 3,  where L 1  is a minimum distance between the developer carrying member and the accommodating casing in the first opposing region, L 2  is a minimum distance between the developer carrying member and the cover portion in the second opposing region, and L 3  is a minimum distance between the cover portion and the accommodating portion opposing the cover portion.

Claim (Index 8):
An image forming apparatus comprising:\n a rotatable image bearing member; an accommodating casing configured to accommodate a developer; a rotatable developer carrying member provided in said accommodating casing and configured to develop, in a developing region, an electrostatic latent image formed on said image bearing member, wherein a rotational direction of said image bearing member is opposite to a rotational direction of said developer carrying member; a regulating portion provided below said developer carrying member with respect to a vertical direction and configured to regulate an amount of the developer on said developer carrying member; a magnetic flux generating portion provided inside said developer carrying member and including a first magnetic pole provided downstream of the developing region with respect to the rotational direction of said developer carrying member and a second magnetic pole which is provided adjacently downstream of said first magnetic pole with respect to the rotational direction and which has a polarity identical to a polarity of said first magnetic pole; and a cover portion provided downstream of the developing region and upstream of a maximum magnetic flux density position of said second magnetic pole with respect to the rotational direction, said cover portion being disposed between said casing and said developer carrying member over a rotational axis direction of said developer carrying member with a gap between itself and said casing and with a gap between itself and said developer carrying member, wherein a first opposing region between an inner surface of said casing and said developer carrying member is in a side downstream of the developing region and upstream of a second opposing region between said cover portion and said developer carrying member with respect to the rotational direction; and a wall portion projecting from an upstream end portion of said first opposing region with respect to the rotational direction upwardly in a vertical direction and opposing said image bearing member with a gap therebetween over a longitudinal direction of said image bearing member.
